Exchange Recovery | Exchange Server Recovery tool to recover & convert edb to PST file

Corruption of Exchange Server database can be a sign of data loss problems

2012-01-18T03:00:00.000-08:00

MS Exchange server is widely used to carry out effective email-based collaborative communication. It keeps all user emails and other directory information in a transaction-based and fault-tolerant database.
However, you may occasionally encounter Exchange server failure due to various reasons. At the time of failure, it uses the transaction log for reconstructing data. Sometimes, data corruption is severe and cannot be resolved using the manual methods provided by Exchange server. In such circumstances, you need to go for Exchange server recovery through a reliable third-party utility.

Exchange server contains user data in the form of EDB files. The corruption in EDB files may occur due to myriad factors, such as virus infection, abnormal system shutdown, user errors, etc. There are typically two types of Exchange server database corruption, i.e. 'Logical corruption' and 'Physical corruption'.

Logical corruption is generally seen as a result of storage corruption or database engine failure. This may damage your folders, mailboxes, emails, and attachments. Physical corruption is caused due to a hardware defect or failure. In this case, the whole database becomes corrupt on the hard drive.

In this section of the article, we will discuss about logical database corruption. Various factors responsible for logical corruption of a database in MS Exchange server are described below:

1. Edb.log file deletion: The deletion of log file (Edb.log) can make a database logically corrupt.
2. Write Back Caching: Unprotected write-back caching against the log drive also results in logical database corruption. You need to have a good battery backup to protect the data in cache.
3. Use of Eseutil/p command for repairing: Exchange Server database may get logically corrupt or damaged by running the eseutil /p command.

Below stated are some of the methods that can be used for fixing logical database corruption:

1. Perform offline defragmentation with the help of the (eseutil/d) command in order to resolve the problem of inefficient usage of space. After doing offline defragmentation, run an integrity check tool (Isinteg -fix) to repair logical corruption
2. If a backup is maintained on any other storage device, then the backup can be used for restoring the corrupt database.

Additionally, there are several third party Exchange recovery tools that have been introduced in the market by various companies to solve the Exchange error codes, appeared due to corruption or any other reasons. Such tools are proficient in resolving logical corruption issues in Exchange server and restoring various mailbox items, such as emails, contacts, appointments, etc.

Stellar Phoenix Mailbox Exchange Recovery is an advanced Exchange database recovery utility that safely repairs corrupt EDB files of MS Exchange 2010. 2007, 2003, 2000, and 5.5. Moreover, the software supports selective recovery of user mailboxes.

Perform Exchange Recovery if inconsistency is depicted in Exchange Server database table

2012-01-09T00:19:00.000-08:00

Microsoft Exchange Server is considered as the backbone of a business organization. However, Exchange server databases become susceptible to corruption due to myriad factors, such as abrupt shutdown of the server, power surges, hardware failure, virus infection, etc. Because of corruption, Exchange Server database starts exhibiting bad behavior. Exchange Server database consists of several tables. These tables consist of one or more trees and hold records and columns that are recognized as MAPI properties. But at times, Exchange Server fails to identify these database tables or simply marks them as invalid. When an attempt is made to access data from database, errors are observed in the application event log. To effectively overcome this problem, you need to go for Exchange Recovery through a reliable third-party utility.

Discussed below is an event ID that is viewed in the application event log of Exchange Server 2000 after encountering corruption in the database:

''Information Store (2412) Data inconsistency detected in table Msg of databaseE:\Program Files\exchsrvr\mdbdata\priv4.edb (0,524957). For more information, click http://search.support.microsoft.com/search/?adv=1.''

Furthermore, if you try to check database integrity by running the 'eseutil/g command, you come across the following error:

''The Database is corrupted.''

Cause:

The above errors occur due to Exchange server database corruption. The primary causes responsible for corruption include defective hard disk or disk controller, anti-virus software, power surges, etc.

Solution:

In order to resolve the above problem, you should first verify your system log. If the problem is with your hardware, controllers, file systems, or drives, then simply replace the hardware and update the hardware system files.

In case of running database, transfer all mailboxes to some other store, remove the affected database, create a new one, and then transfer the mailboxes back.
In case the Information store database fails to mount, it is advised that you should use an online backup to restore the database.

If the backup is unavailable, then you have to follow a different approach. Use the eseutil/p command for database repair. Now, defragment the database using eseutil /d command and then, repeatedly run the 'isinteg -fix' command.
If the problem still persists, then simply export all data to PST files with the help of the 'Exmerge' tool, delete the database, make a blank database, and import the data to the blank database using 'Exmerge'.

However, if the above resolution steps are unable to solve the problem, take help of a competent Exchange database recovery tool. These third-party tools are capable of safely repairing corrupt EDB files and restoring them as distinct PST files for each user mailbox.

Stellar Phoenix Mailbox Exchange Recovery is a comprehensive EDB repair tool that efficiently repairs Exchange server databases created in MS Exchange 5.5, 2000, 2003, 2007, and 2010. The software facilitates selective recovery of user mailboxes and is compatible with Windows 7, Vista, Server 2003, XP, and 2000.

Antidote for Exchange Server Error 8197

2011-12-30T19:48:00.000-08:00

Microsoft Exchange Servers are deployed in establishments in copious numbers across the globe. One of the trusted solutions for handling business emails, MS Exchange Servers are the backbone of enterprises that manage vital emails and act as a repository for user mailbox and its data.

Exchange Servers succumb to corruption on the grounds of virus attack, software or hardware malfunction, abnormal termination of the Information Store Service, dirty shutdown due to power failure etc. These multifarious reasons play a major role in the corruption of Exchange Server database file (EDB).

A common error message encountered by the Exchange Server users is:

“Event Type: Error
Event Source: MSExchangeFBPublish
Event Category: General
Event ID: 8197
Date: MM/DD/YY
Time: XX:XX:XX AM
User: N/A
Computer: Server Name
Description:
Error initializing session for virtual machine Server Name. The error number is 0x80040111. Make sure Microsoft Exchange Store is running. Also, make sure that there is a valid public folder database on the Exchange server.”

The aforementioned error message appears in the application log every 25 minutes irking the Exchange User time and again by hampering his work. This error message appears due to the unbinding of the Global Catalog Server by the background tasks of the free/busy folder to process updates. The free/busy task in Exchange Server deploys Windows's Operating System's referral mechanism to locate the Global Catalog Servers, contrary to the other tasks that rely on DSACCESS mechanism. These two processes have different algorithms that results in the occurence of the Exchange Event ID 8197.

To resolve this error, find out the Global Catalog Server that is not binding here:

HKEY_USERS\.DEFAULT\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\ExchangeAdmin

The registry key should be different from this:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Exchange\Exchange Provider\DS

By using the general connectivity troubleshooting steps for the Global Catalog Server that is unbinding, the above problem can be resolved. For more detail information about this error, you may see: http://blogs.technet.com/b/exchange/archive/2005/07/29/408394.aspx

However, if the above problem still persists, you may use a dexterous third party tool.

Exchange BKF Recovery saves precious data when restoration through backup goes up in smoke

2011-12-22T00:15:00.000-08:00

It would be an under statement if I said that backup files are vital for every Microsoft Exchange Server user. Many a times, owing to unforeseen events, data loss situations strike an Exchange user like a bolt from the blue, leaving him in miserable conditions. If being an Exchange user you have inestimable data and information stored on the server that suddenly becomes inaccessible or lost due to a catastrophic malfunction the whole foundation of the organization is driven towards an irrecoverable doom.

The aforementioned scenario is just one of the few situations where without a handy backup file to restore the data, a corporate would breath its last breath. This clearly signifies the undeniable importance of BKF files in the world of Microsoft Exchange Servers.

However, there is another catch. To restore precious emails, contacts, calendar items, attachments, appointments, notes, tasks and journals, the data has to be recovered from an updated backup file. But the scenario is drastically altered when even the BKF file fails to restore the data. One of the chief reasons that play their part in this blotch is BKF file corruption. The Exchange Server BKF files knuckle under corruption due to hardware crash, software failure, virus attack, missing catalog files, dirty shutdown etc.

Periodic data backup is maintained by the Exchange System administrator as the benefactor to recover vital data and information at times of Exchange database failure. If the BKF file falls prey to corruption, all is lost. The only light at the end of the tunnel is Exchange BKF Recovery using third party recovery tools.

Exchange BKF repair can bring back all the lost data as usable BKF file that can get its user up and rolling in a flash. A trusted solution is “Stellar Phoenix Exchange BKF Recovery” from “Stellar”, one of the leading names in the world of data recovery.

Whatever be the size of the Exchange BKF file, this powerful utility can repair even the large sized backup files without a hitch. Designed for both novice users and tech savvy professionals, the Exchange BKF Repair tool is compatible with Windows 2000, XP, 2003, Vista and Windows 7.

What to do when Exchange Server Recovery becomes quintessential

2011-12-12T19:08:00.000-08:00

Microsoft Exchange Servers are designed to work with various email-client applications, such as MS Outlook, Entourage and more. One of the main stream email clients deployed across the globe, Microsoft Outlook is the choice of the major chunk of business enterprises. MS Exchange Servers not only act as backup but are the epitome for managing business communication via emails.

Though Exchange Servers have evolved remarkably over the years, but even today, they are not unblemished. Like the other side of the coin, despite being highly efficient and feature-rich, they are prone to multifarious error and corruptions that beget a situation of data loss and inaccessibility.

Let us envisage a particular scenario, when a user attempts to access his mailbox on the Exchange Server and encounters an error message that looks like this:

“s1041724…..internal processing error”

The first resolve that comes to the mind is the Exchange Server Recovery using 'Eseutil.exe' utility. In most cases, ESEUTIL effectuates recovery of Exchange Server and the user mailboxes with their vital data become accessible again. Nonetheless, at times Eseutil fails to perform Exchange Server recovery and barrades the following error message:

“Operation terminated with error -1206 (JET_errDatabaseCorrupted, Non database file or corrupted db) after 1.281 seconds.”

These are cases of severe database corruption that can be caused due to excessive fragmentation, which can not be resolved through soft recovery. When soft recovery fails, a hard recovery is executed using 'Eseutil/p'. However, extreme cases of corruption debar the process of database defragmentation and another error message pops up saying:

“Operation terminated with error -2211 (JET_errSLVHeaderCorrupted, SLV file header contains invalid information) after 0.438 seconds.”

The above error message signifies that either the Exchange database is corrupt or EDB file header is damaged. For a Exchange user, this situation is pathetic leaving him devoid of all his precious emails and Outlook items such as calendars, tasks, attachments, notes, journals, To-do lists and contacts.

A prudent solution for the aforementioned error is Exchange Server recovery using third party tools. An efficacious exchange recovery tool is “Stellar Phoenix Mailbox Exchange Recovery”.

Crafted with highly advanced algorithms, this software provides the option to recover all or the desired user mailboxes from the corrupt or damaged EDB file without a hitch. The trial version of the software shows a preview of the user mailboxes and their components that it can recover. This Exchange database recovery utility is completely risk free and is capable of performing selective recovery even on the excruciatingly corrupt/damaged .edb file.

How to repair Exchange Server corruption resulting from JET Engine Errors

2011-11-27T21:01:00.000-08:00

JET Engine is a vital functional element of Microsoft Exchange Servers and is prone to corruption. When the JET Engine becomes corrupt, the following error code flashes:

“100 0xFFFFFF9C JET_errRfsFailure JET_errRfsFailure 4294967196”

Frequent causes of MS Exchange Server JET Engine corruption are:

Bad sectors on hard drive due to which the database reads incorrect information
Corrupt database file pages
Hardware failure due to wires, routers and cables
Dirty shutdown due to power failure
Virus attack or malfunction due to a malicious program
Errors due to increasing file size

In the lion's share of Exchange Server corruption cases, immediate data recovery becomes imperative, as in the corporate environment, loss of vital emails and user data can be disastrous. When Exchange Server goes down owing to JET Engine errors, the first resort for the Microsoft Exchange Server user becomes the use of Eseutil.exe and Isinteg.exe utilities to repair the corrupt Exchange Server database file EDB.

But what not many of these users realize is that applying the in-built utilities to the corrupt or damaged EDB file, sometimes aggravates the EDB file corruption. These utilities sometimes delete valuable files whose loss renders it quite impossible to recover the Exchange database intact. Due to missing vital files, the Exchange database can not be rebuilt.

A wise approach in cases of JET Engine errors that look like: JET_errRecordNotFound is to first take a backup copy of the original Exchange Server database EDB file and then perform the recovery using ESEUTIL and ISINTEG.

In certain scenarios, the above mentioned utilities are unable to repair the EDB file. This is where the third party tools save the day. Teeming EDB repair software are up for grabs on the Internet that dexterously recover the data from the corrupt .edb file and restore it as usable PST files.

How to solve Exchange Event 9175 ?

2011-11-03T21:36:00.000-07:00

Exchange Mailbox Store is a very important component of the server and essential to proper functioning of an Exchange server. Each Exchange mailbox store is constituted of two important files named Priv.edb and Priv.stm. The EDB file is an ESE database file and also known as MAPI based database. It stores all MAPI messages, e-mail attachments and other important data. The STM file, known as streaming file, is also an ESE database file and stores primal internet content. When Microsoft Exchange Server is started, ESE determines the state of database whether it is in Consistent or Inconsistent. If ESE finds any inconsistency in Exchange database, it performs soft recovery. However, when a severe corruption occurs in a mailbox store, you will no longer be able to work with Exchange database smoothly and when you attempt to mount the database, you may get some error messages.

For example, consider a scenario wherein you are using Exchange server 2000 or 2003 and you encounter some corruption problem in your database. When you try to mount the Exchange mailbox store, you may receive the below event log description mentioned in the application event log:

Event Type: Error
Event Source: MSExchangeSA
Event Category: MAPI Session
Event ID: 9175
Date: 7/9/2001
Time: 5:32:11 PM
User: N/A
Computer: XYZ
Description:
The MAPI call 'OpenMsgStore' failed with the following error:
The Microsoft Exchange Server computer is not available. Either there are network problems or the Microsoft Exchange Server computer is down for maintenance. The MAPI provider failed.
Microsoft Exchange Server Information Store
ID no: 8004011d-0526-00000000

Causes:

Some of the reasons for the occurrence of above event are:

Most of the time this event occurs if an Exchange Mailbox store failed to mount.
System Attendant (SA) is attempting to make an Offline Address Book (OAB).
Information Systems store services are stopped.
Corruption in Exchange Mailbox store.

Solution:

You can try the following solution:

Check whether Exchange Information Store service is running or not. If the Information store is not running, try to start it.

If the Information store is working and the event is still logged. Confirm that the default Exchange mailbox store is mounted. If it is not mounted, try to mount it.
If the Information Store is corrupt, you will need run built-in ESEUTIL/P command line utility.

If the above said repair utility fails to repair the corrupted Information Store, then you'll have to use a third-party Exchange recovery application to repair the damaged Exchange Information Store.

Such third party Exchange Server Recovery software are specifically developed to recover data from logically or physically damaged Exchange database (EDB) file. The repaired and recovered edb file can be saved at default or user's specified location.

Are you in a need to rectify an Error message while using an Exchange Server?

2011-10-07T20:47:00.000-07:00

Microsoft itself provides an inbuilt utility named as Eseutil/p that helps to repair the corrupt Exchange Server database at both page and table level. Almost all the cases of database corruption, can be easily solved with the repair utility. But, still some cases of severely corrupt Exchange Server database cannot be solved with the help of an Eseutil/p utility. An inbuilt utility starts throwing an error message. Corrupt Exchange Server database remains corrupt and data saved in the Exchange Server database remains in inaccessible state. Well, a backup is a best solution to overcome the problem of data inaccessibility. However, in case of invalid backup, the best solution is the use of an Exchange Recovery tool.

Discussed here is an error message that comes up on the screen at a time Exchange Server gets corrupt or damaged. When an attempt is made to repair the Exchange Server database through Eseutil/p utility, an overall attempt to open it fails. That, error message appears to be like this:

“Operation terminated with error -1605 (JET_errKeyDuplicate, Illegal duplicate key) after xxx.xxx seconds.”

Data saved in the database become totally inaccessible after the occurrence of above error message. Same error message bothers every time. It is quite intermittent.

Cause:

The fundamental cause responsible for the occurrence of above error message is the incorrect rebuild of B-trees by the repair program. Incorrect rebuild of B-trees will alter the whole meta data structure of the database, bringing it in a permanently non-repairable state.

Solution:

For solving the above error message, and to access the data of the records saved in the database, it becomes necessary to obtain the latest service pack of Microsoft Exchange Server 5.5, and after obtaining it. Try to perform repair of the Exchange Server database. However, if the database still remains unrepaired even after the installation of service pack, then a third party Exchange database Recovery tool becomes a need of hour.

In market, ample of software are available that does the repair of corrupt Microsoft Exchange Server database easily and within a small period of time. These tools perform Exchange server recovery, if the corruption is logical. These third party tools have been developed under the assistance of professionals.

These tools have read-only nature, well described procedures and effective recovery abilities.

How to resolve Exchange server error “The database files in this storage are inconsistent” ?

2011-09-18T23:45:00.000-07:00

Microsoft Exchange Server is a communication application which is widely used by many small to large organization. This server-side application provides complete network sharing and effective management of both email-clients and its individual users. The Exchange Server application stores all the data like emails, attachments, contacts, notes, calendar entries, sent items etc. in an information store database file that is known as .edb file. Sometimes, you fail to mount the Microsoft Exchange database because of corruption or any other reason and get some undesirable error messages.

The causes which lead to database file corruption and other damages are file's header corruption, human errors, virus attack, hardware error, power outage and more. Due to the corruption in Exchange database file, the users of MS Outlook fail to access their emails and other items. In such situation, you should try to find the reason of corruption and take appropriate action to repair the damage Exchange Server. However, if you are not able to do this, then you can use a third-party Exchange Server recovery solution to repair and recover data from corrupt EDB file.

Consider a scenario wherein you are using Exchange server 2000, then you try to mount the Information Store database file in Exchange Server but are unable to do so and an error message appeared, which says:

“The database files in this storage are inconsistent
Id no: c1041739”
In addition, every time when you attempt to mount a database, you will find the following error entries in the application log:

The read operation will fail with error %7. If this condition persists then please restore the logfile from a previous backup.

Cause:

The reason for this problem is that either the Exchange mailbox store database or public store database is not in a consistent state.

Resolution:

To resolve this problem and access the damaged .edb file, there are some built-in tools provided by the Microsoft to check and repair the Exchange database. You should either repair or restore the corrupt Exchange database file by using the appropriate utility. You can do this by applying the following methods:

1) Check the State of Database:

Use the following command to check the consistency of the database:
eseutil /mh "drive:\program files\exchsrvr\mdbdata\database_name.edb"

If the Exchange database file is not a consistent state, the following message displays on the screen:

State: Dirty Shutdown

2) Repair or Restore the Exchange database:

If the database is not in a consistent state, you need to repair or restore it.

Restore from backup: Following steps describe how to restore a database from the backup file:
1. Move or rename the E00.log file. By default, the location of this file is Drive:\Program Files\Exchsrvr\MDBDATA folder.
2. Restore the storage group and the log files.
3. When the storage group is completely restored, try to mount the database.
Repair EDB database file: Use the following steps to repair the database file:
1. Open Command Prompt Window
2. Move to the Drive:\Program Files\Exchsrvr\Bin folder.
3. Execute the following command:

eseutil /p “drive:\program files\exchsrvr\mdbdata\database_file_name.edb”

Run the following command to defragment and rebuild the Exchange database file:

eseutil /d /t:x “drive:\program files\exchsrvr\mdbdata\database_file_name.edb

Verify the consistent state of the database, type the following command and press 'Enter':

eseutil /mh “drive:\program files\exchsrvr\mdbdata\database_file_name.edb”

If the database is in a consistent state, then the following text line is appeared:

State: Clean Shutdown

Use the Infromation Store Integrity (isinteg.exe) utility with the below mentioned switches to repair the logical corruption:

Isinteg –s exchange_server_name –fix –test alltests

Run this command until you get zero errors and zero fixes for the same database in the output.

Try to mount the Exchange database file.

Exchange Information store is the most critical constituent of Microsoft Exchange Server. Sometimes, when the Exchange Server is hit by any crashing or corruption issue, information store also gets affected. In order to access your mailbox, you need to mount the Information store. However, under some corruption or any damage situation, the mailbox store or public store denies to mount. In this case you will not be able to access your information such as emails, notes, contacts, images, attachments and more, stored in Exchange Mailbox. These Exchange mailboxes are connected to Information store database that keeps all data of active directory. The Mbconn.exe file is used to connect these mailboxes to Active Directory accounts.

Sometimes, when this MBCONN file gets corrupted and you try to use your mailboxes through an e-mail client, you may experience that Server is not responding in a proper way. The corruption in mbconn.exe file directly affects the connection between Information store and the user mailbox. Additionally, you may experience some problems like:

Mbconn sets uppercase legacyExchangeDN delimiters, due to which the email clients unable to publish the information.
The Mbconn utility abruptly exits, when you access file browse dialog boxes.
Process of importing the Ldifde fails because of improperly formatted entries in the Mbconn export file.
You may encounters "No such object" or "No private databases found on this server" error messages.
The reconnections of Exchange mailboxes are reported as failures, even though the reconnections actually worked.

Moreover, if an Exchange server administrator starts Exchange System Manager (ESM), and then he tries to run the Cleanup Agent to test the connection state of all mailboxes, the Cleanup Agent fails, and he gets the following error message:

“An internal processing error has occurred. Try restarting the Exchange System Manager or the Microsoft Exchange Information Store service, or both.
ID no: c1041724”

The aforesaid problems are occurred only if the Mbconn.exe file is lost or has been corrupted. To resolve these problems, you need to get the latest service pack of the Exchange server and install it.

This behavior of MS Exchange Server depicts all your precious information inaccessible and leads to critical data loss. In order to get your data back, you require to opt for an Exchange Server Recovery software, if the backup is not updated.

How to Solve Exchange Server Error 1053

2011-07-28T00:08:00.000-07:00

Performance of MS-Exchange Server totally depends on the System Attendant service. Without it Exchange related services stop working. Like, Exchange server database cannot be mount, unless and until Exchange System Attendant service is not running. Information store of Microsoft Exchange also depends on Exchange System Attendant service. Data of Information store cannot be accessed. To get rid of problem related to information store and to access data of it, you can use a backup. If backup falls short to recover, then you can go for a third party Exchange database recovery tools.

To illustrate above issue, let us consider a scenario. When you make an attempt to start the MS-Exchange System Attendant service on a server, that is executing MS-Exchange Server 2000 or 2003, MS-Exchange System service does not start. In addition to this, you may receive the below stated error message on the screen that looks exactly same as given below:

“Could not start Microsoft Information Service on local
computer, Error 1053: The service did not respond to the start or control
request in a timely fashion”

Following event ID comes on the screen in the system log:

“Event Type: Error
Event Source: MSExchangeSA
Event Category: General
Event ID: 9188
Date:
Time:
User: N/A
Computer:
Description:
Microsoft Exchange System Attendant failed to read the membership of group 'cn=Exchange Domain Servers,cn=Users,dc=domain,dc=root'. Error code '80072030'. Please check whether the local computer is a member of the group. If it is not, stop all the Microsoft Exchange services, add the local computer into the group manually and restart all the services.
After the above error message pops up on the screen, the data saved in the Information Store becomes inaccessible.”

“Event Type: Warning
Event Source: MSExchangeSA
Event Category: General
Event ID: 9157

Time:
User: N/A
Computer:
Description: Microsoft Exchange System Attendant does not have sufficient rights to read Exchange configuration objects in Active Directory. Wait for replication to complete and then check to make sure the computer account is a member of the "Exchange Domain Servers" security group.”

After the occurrence of above error message, data of the Information store becomes totally unapproachable.

Cause:
Above erroneous situation occurs when the System Attendant service starts, it finds the below stated groups in only the container of default Users:

Exchange Enterprise Servers
Exchange Services
Exchange Domain Servers
If the groups are absent, the System Attendant service verifies non-existence of group. Therefore, if these groups are not present in the Users container during the beginning of System Attendant service, it fails to start.

Other reason might be the corruption of Exchange Server.

Solution:

Follow the below steps to solve the above problem and to access data of Exchange Server:
1.Transfer the below mentioned groups to default Users container:
- Exchange Enterprise Servers
- Exchange Services
- Exchange Domain Servers
2.Start the System Attendant service again.

If the problem still persists, then it means that Exchange Server is severely corrupted. You have to repair the corrupt or damaged Exchange Server database file with the help of an inbuilt 'eseutil/p' command. It might be possible that command does not work then you can restore the file from a latest backup. If backup is unavailable, then you have a last option of a third party Exchange Server Recovery.

Exchange Server stops working because of some hard ware issues, driver issues, Exchange Server corruption. Many times, reasons are described in the event ID itself. The best way to sort out the corruption related problem is a third party Exchange Server Recovery software.

For instance below error message might get received when MS-Exchange Server information store fails to start, or it stops working if it is already in use. Event ID mentioned below gets received like this:

''Event ID: 145
Source: ESE97
Category: General
Description: MSExchangeIS ((%pid%) ) The database engine could not access the file called %database path%\edb.log.''

Other reason might be the corruption of Exchange Server information store.

Solution:
For solving the above problem, do a installation of AV software, backup, or other software so that any of the data files cannot get directly accessed on the Exchange Server. Do not include all \exchsrvr directories from being scanned by file based virus scanning software. This is advisable because Exchange aware AV scanning software do not access the files directly and do not cause this issue.

For taking the backup of Exchange server files, firstly stop the Exchange Services. Exchange aware backup product can be used to back up the Exchange databases in a online mode. No file contention problem will be faced.

Exchange Server Recovery for Corrupt Priv.edb file

2011-04-11T02:37:00.000-07:00

Public folder store and Mailbox store are the components of Exchange store. These stores further contain different files in them. In mailbox store, the files are priv.edb, priv.stm and in public folder store, the files are pub.edb and pub.stm. Both these Exchange store components are vulnerable to corruption and their corruption can stop the working of Exchange store service, which can lead to complete inaccessibility of Exchange Server database. To get over the corruption of mailbox store and public folder files, you can run an utility known as 'eseutil/p'. However, in some cases, this utility does not prove helpful to repair damaged database. For such cases, the last solution is a third party Exchange Server recovery tool.

Suppose, you use MS-Exchange database of around 300 GB. The Priv.edb file of your Exchange Server database has got corrupted and you executed the 'eseutil/p' command to resolve the issue. The repairing process by 'eseutil/p' command proceeded successfully, but suddenly stopped with an error message. The error message can be written as below:

“Assertion Failed: dPercentage >=0, file G:\ese97\src\eseutil\edbutil.cxx, line 563.”

Repair process remained incomplete and the data of Microsoft Exchange database became totally inaccessible. After that, the above error message appears every time you try to repair the Exchange database.

Why the error is coming?

The cause, that is responsible for the above stated error message is the corruption of priv.edb file and 'eseutil/p' utility falls short to solve the problem of corruption.

How the error can be solved?

For resolving above error message and to make the data of Exchange Server accessible, You have to follow the below suggestions:

Use the latest or highest service pack level for Exchange Server 5.5.
If, the problem still remains the same, you can use an up-to-date backup to restore the database.

If backup is deficient to restore the data or is not available, then you need to go for a third party Exchange Server Recovery product.

Resolving Event ID 9175 and 486

2010-08-21T22:15:00.000-07:00

Sometimes when you try to mount a database on a server that is running Microsoft Exchange Server, and instead receive the following error message:

“An internal processing error has occurred. Try restarting the Exchange System Manager or the Microsoft Exchange Information Store service, or both.
ID no: c1041724
Exchange System Manager”

Additionally, the following event is logged in the Application log:

Event Type: Error
Event Source: MSExchangeSA
Event Category: (14)
Event ID: 9175
Description: The MAPI call ‘OpenMsgStore’ failed with the following error: The Microsoft Exchange Server computer is not available. Either there are network problems or the Microsoft Exchange Server computer is down for maintenance. The MAPI provider failed. Microsoft Exchange Server Information Store ID no: 8004011d-0526-00000000

or

Event Type: Error
Event Source: ESE
Event Category: General
Event ID: 486
Description: Information Store (3932) First Storage Group: An attempt to move the file “E:\Program Files\Exchsrvr\mdbdata\E00.log” to “E:\Program Files\Exchsrvr\mdbdata\E000080A.log” failed with system error 2 (0×00000002): “The system cannot find the file specified.” The move file operation will fail with error -1811 (0xfffff8ed).

Cause

1. Error 1811 relates to JET_errFileNotFound. This issue may pop up in an Exchange log (E00.log) file that has a mismatching signature and LGeneration. If E00.log file has a mismatching signature, the information store won’t mount even if the databases are consistent.
2. If an anti-virus program quarantines, deletes or interferes the current Exchange log file.

How to Resolve?

To resolve this issue, ensure the anti-virus is not configured to scan the Exchange Server directories. Check the log files of the anti-virus program to verify whether the Exchange log file was quarantined or deleted.

1. If quarantined, recover the Exchange log file by executing the following steps:

a) Recover the Log to folder which contains production files
b) Start MS Exchange Information Store Service. In case other Exchange log files are not missing, the database will mount. In case more log files are found to be missing, check the missing log files in the quarantine folder. If you cannot find the files, follow the next step.

2. If deleted, recover the Exchange log file by following these steps:

a) Move all the inconsistent databases to backup folder
b) In case, new E00.log file is made, move it to the backup folder. Also, move E00.chk and copy the existing files.
c)Rename last E00*.log file as E00.log
d) Restore database from backup.

If you do not have a backup, you must consider using third-party Exchange Server recovery software to bring EDB database files to consistent state.

2010-08-12T23:26:00.000-07:00

Are you unable to mount EDB (Exchange Database) database file on the MS Exchange Server 2007 system that is being used in your organization? If yes, then there is a very prominent possibility that the EDB file is corrupt thereby disabling you from mounting it. In such cases, you should try to find out the exact cause of corruption and try to eradicate that issue. In case, nothing is succeeding then you should use a professional Exchange repair software to recover the trapped data.
Consider a similar situation in which you are unable to mount the database on MS Exchange Server 2007. The following error message is displayed:

“An internal processing error has occurred. Try restarting the Exchange System Manager or the Microsoft Exchange Information Store service, or both.
ID no: c1041724
Exchange System Manager”

In addition, when you check the error log the following event is logged:

“Event Type: Error
Event Source: ESE
Event Category: General

The move file operation will fail with error -1811 (0xfffff8ed).”

Cause:

You may have run the eseutil /p command on the damaged databases. This problem has occurred because the transaction log files were not removed during the process.

Resolution:

First of all, you should check whether eseutil was run on this system at all or not by performing the following steps:
1.Click Start | Run.
2.Enter 'CMD' in the 'Run' box and press 'Enter' key. The Command Prompt window will be displayed.
3.Enter the following command:
4.c:\program files\exchsrvr\bin\eseutil /mh "c:\program files\exchsrvr\mdbdata\name of Exchange database.edb"
5.Check the repair count field. If it is 0, then the eseutil /p command was not run. For a non-zero count, eseutil /p command was run on the database.

Now, you can transfer the transaction log files to another folder if the database is in a clean shutdown state. To check this condition, you should perform the following steps:

1.Click Start | Run and enter 'cmd' in the 'Open' box and click OK.
2.To check the private information store, enter the following command in the Command Prompt:
3.c:\program files\exchsrvr\bin>eseutil /mh "drive:\program files\exchsrvr\mdbdata\priv1.edb"
4.To check the public information store, enter the following command in the Command Prompt:
5.c:\program files\exchsrvr\bin>eseutil /mh "drive:\program files\exchsrvr\mdbdata\pub1.edb"
6.Analyze the consistency check results. If the database is consistent, then all the transaction log files are moved to the information store.
7.Transfer all the log files from the directories to a backup folder.
8.Now try to mount the database. It should run fine now.

In the event of still unable to mount the database, the only way of resolving this problem is to use a third-party MS Exchange repair software. These tools are highly interactive in nature that do not damage the EDB files while scanning them.

It uses fault-tolerant, transaction-based databases to store messages and other information before it is applied to the database. If the Exchange Server experiences a power outage or an unexpected system failure, it uses transaction log files to reconstruct the data which is already accepted by the server but not yet written to the database. At times, when being an administrator, you are unable to restore corrupt database from the last available backup, it becomes quite essential for you to grab advanced and professional Exchange Server recovery software.

If Outlook 2003 has been installed on Exchange Server/domain controller, there is a need to to change the security settings of 'log on network security' to 'Kerberos.'
Delete old Outlook profile and create a new profile.
Check Exchange database by using Eseutil and Isinteg utility

Information store corruption: ' Error 4294966746...' in Exchange Server 5.5

2010-07-05T23:11:00.000-07:00

Source: http://hubpages.com/hub/recover-corrupt-edb

Information store is the core data storage repository for Microsoft Exchange Server. It constitutes both mailbox store and public folder store data. At times, the information store in Exchange Server may get corrupt or inaccessible. The corruption may be caused by a variety of reasons including sudden or unexpected loss of power, faulty hardware which has written information to the disk incorrectly, and others. In order to make it accessible and continue normal operations, it becomes important to troubleshoot the problem by using appropriate Exchange Recovery solutions. If no concrete solution seems working, an administrator can go for professional tools.

As an administrator, you may experience the following problems with Exchange Server 5.5:

1.You cannot start MS Exchange Server Information Store service
2.The information store cannot be stopped
3.The CPU usage level remains 100 per cent even when the information store has stopped responding
4.Even after restarting the information store, clients are unable to send or receive e-mails
5.And, when you restore the Exchange Server databases from an offline backup and run the Isinteg utility, you receive the following error:

'Error 4294966746: JET_errDatabaseInconsistent'

Cause

The error surfaces when the information store becomes corrupt. Corruption involves either Priv.edb or Pub.edb files.

Resolution

In order to recover the public and private information stores, you must consider the following Exchange recovery steps:

1.Make a backup copy of the Pub.edb and Priv.edb files
2.Now start the information store and note any error message or event ID which erupts
3.Check the consistency of the information store databases, run Eseutil.exe command by using following commands:
c:\exchsrvr\bin>eseutil /mh ..\mdbdata\priv.edb
c:\exchsrvr\bin>eseutil /mh ..\mdbdata\pub.edb
4.If both the Pub.edb and Priv.edb files are consistent (Output: Clean Shutdown), then move to step 8. If not then try to perform soft recovery of the files to see if you have the copies of the log files that are stored in the Mdbdata folder. You can use the following commands:
c:\exchsrvr\bin>eseutil /r /ispriv
c:\exchsrvr\bin>eseutil /r /ispub
5.If eseutil / r does not send databases to consistent state, then use the following commands to perform hard repair
c:\exchsrvr\bin>eseutil /p /ispriv
c:\exchsrvr\bin>eseutil /p /ispub
6.Delete all .log and .chk files and Temp.edb in the ExchSrvr\Mdbdata folder
7.Check if the Microsoft Exchange Information Store service is running. If it starts successfully, stop the process.
8.Now defragment the database which you just repaired by using the following commands:
c:\exchsrvr\bin>eseutil /d /ispriv
c:\exchsrvr\bin>eseutil /d /ispub
9.Use the Isinteg.exe utility to repair Pub.edb and Priv.edb, using the following commands:
c:\exchsrvr\bin>isinteg -pri -fix -test alltests
c:\exchsrvr\bin>isinteg -pub -fix -test alltests
10.Restart the information store

In case, you are still not able to isolate corruption or overcome the problem, download an advanced Exchange Server recovery application from the Internet.

Fixing 'Unable to Mount the Mailbox Store with error c104173c …' error in Exchange Server

2010-06-25T03:16:00.000-07:00

Information store is the most vital component of Microsoft Exchange. When the Exchange Server is hit by corruption issues, information store also gets affected. It is made up of four database files viz Priv1.edb, Priv1.stm, Pub1.edb and Pub1.stm. When corruption occurs either Prive1.edb or Pub1.edb falls prey to it. In event of corruption, an Exchange administrator can observe various symptoms including the MS Exchange Information Store service won't start, or clients cannot send or retrieve e-mails or abrupt error messages. In order to isolate the issues, the administrator must use the updated backup copy of the database. However, if no backup is available, he should immediately switch to MS Exchange Repair solutions.

Consider a scenario, wherein, you, being the administrator, try to mount the mailbox store in Exchange System Manager, and receive the following error message:

“Unable to Mount the Mailbox Store with error c104173c The Information Store is Busy”

Cause

The above error indicates the possible corruption in one or both edb files (Priv1.edb or Pub1.edb) of information store.

Resolution

In order to troubleshoot the issue, you must perform the following Exchange Repair steps:

1. Run eseutil/mh command in order to determine if the database is consistent
2. If you get the following output 'Clean Shutdown' , move out all the log files from Exchsvrmbddata folder
3. But if you get 'Dirty Shutdown' as output, perform soft recovery by using eseutil/r
4. If database does not come to a consistent state, perform hard repair by using eseutil/p command.
5. If you use the above command, you may lose some Exchange Server data, including the messages that were contained in the log files that were not committed to the information store database. Therefore, it is a wise decision to use a third-party MS Exchange Repair application.

Such tools repair corrupt .edb files safely and employ improved scanning algorithms to recover inaccessible data in a hassle-free manner. Being-read only they do not modify the original content. Therefore, you can use them blindly and isolate the information store corruption issues efficiently.

Compatible with Exchange Server 5.5, 2000, 2003, and 2007, this Exchange repair software recovers all e-mail messages, notes, journals, tasks, contacts and other components.

Restoring corrupt EDB file in MS Exchange Server 2007

2010-06-22T04:32:00.000-07:00

MS Exchange Server is the server side of the client-server, collaborative application from Microsoft. It ably provides standard email features such as emails, contacts, notes, tasks, calendar items, etc. In addition, it provides you the option to access Exchange Server mobile devices and various web-based browsers. It may be notable that the server information is stored in an EDB (Exchange Information Store Database) file. At times the EDB file may get corrupt due to which you are unable to mount the Exchange Server database. These situations may occur due to various reasons such as abruptly exiting the Exchange Server, virus infections, corruption in the database header, hardware issues, etc. Such cases can be handled by using certain in-built methods. If you are not able to resolve the problem, then you should use an EDB Repair Software to repair the corrupted EDB file.

Consider a scenario wherein you have Microsoft Exchange Server 2007 running in your organization. When you try to mount the database that is running on the Server, you are unable to do so. An error message is displayed, that is:

“An internal processing error has occurred. Try restarting the Exchange System Manager or the Microsoft Exchange Information Store service, or both.
ID no: c1041724
Exchange System Manager”

Cause:

There could be the following causes for the aforementioned error message:

1. The eseutil /p command was executed on corrupted databases and the log files were not removed during the process.
2. The eseutil command was executed for an incorrect logfile base as shown in the following example:
eseutil /r three-character logfile base name

Resolution:

To resolve this problematic situation, you should perform the following methods for each of the mentioned cause:

1.Resolution for Cause 1: To do this, you should ensure two things:

A) Whether the eseutil /p command was run: This can be done by using the following command in the Command Prompt:
“c:\program files\exchsrvr\bin\eseutil /mh "c:\program files\exchsrvr\mdbdata\name of Exchange database.edb”
i. If the repair count is 1, then this command was run on this database.

B) If the database is in a clean and consistent state: To do this, you should perform the consistency check on the databases. If the database is consistent, then you should move the log files to a backup folder and then mount the databases.

2. Resolution for Cause 2: You should provide the correct parameter to run the eseutil command. For example,
“eseutil /r e00”

Once you perform the mentioned methods, try to mount the database. You will that the problem is now rectified. However, if it is not so then you should use a third-party Exchange Database Repair to extract the corrupted EDB files. Such .EDB repair tools are read-only in nature and are able to convert the EDB files to independent PST files using fast yet sophisticated scanning algorithms.

Performing Exchange recovery when database exceeds 16 GB in MS Exchange Server 2003

2010-06-08T23:17:00.000-07:00

MS Exchange Server is the server side of the client-server application from Microsoft. It extensively supports emailing, managing calendar entries, contacts, tasks, etc. Besides this, it also supports access through mobile and web-based browsers. All such Server information is stored in an EDB file, which sometimes get corrupted making it difficult to mount the Server database. Such corruption scenarios can occur due to various reasons such as database header corruption, hardware issues, abruptly exiting the Exchange Server, etc. In such cases, you should try out appropriate corrective measures. However, if you are not able to sort out the issue then you should use an Exchange Recovery software to do the needful for you.

Consider a scenario wherein you are using MS Exchange Server 2003. One day, when you started the Exchange Server you were unable to mount the database. You check the Application event log and find the following event ID that suggests the possible cause of this situation:

“Event Type: Error
Event Source: MSExchangeIS
Event Category: General
Event ID: 1112
Description: The database "Mailbox Store (Server Name)" has reached the maximum allowed size. Attempting to unmount the database.”

Cause:

The cause of this situation is that the Exchange Server database of Exchange Server 2003 has reached the permitted limit of 16 GB.

Resolution:

To resolve this situation, you should perform the following methods:

1. You should upgrade to Exchange Server 2003 Service Pack 2, as then you would have the option to increase the database size limit to 18 GB.
2. If you have the administrative rights to control the Exchange Server, then you can increase the size of the database by 1 GB for the time being. Then, remove the not-so-necessary content from the database. After this, you should defragment the database to bring it back to the stipulated size limit of the database size.
3. Mount the database using the Recovery Storage Group feature, and then try to extract the EDB from the mailboxes using the Microsoft Exchange Merge Wizard (Exmerge.exe) utility.

Using the aforementioned methods, you can bring the size of the EDB under control and use the Exchange Server as before. However, if you are not able to address the situation then you should use a third-party Microsoft Exchange recovery software to do the needful for you. Such read-only tools are able to perform Exchange Server Recovery without overwriting the original contents.

Exchange Server Database Fragmentation Fails with Misleading Errors

2010-06-06T23:13:00.000-07:00

Microsoft Exchange Server database consists of two common databases, known as Priv.edb and Priv.stm. These database contains all your significant emails, notes, contacts, tasks, journal, attachments and more. If the Exchange Server database come across any sort of database inconsistency and integrity problem, Eseutil.exe utility can help you to fix the problem. It can also be used to repair the damaged database and defragment it. However, in some cases, this utility can not perform the expected tasks successfully and database remains in inaccessible state. In such cases, you are required to carry out Exchange Recovery to work around the problem.

When you attempt to manually defragment the STM (streaming) file of Exchange Server database, you might encounter the below error message:

“Operation terminated with error -2231 (JET_errSLVStreamingFileInUse, The specified streaming file is currently in use) after 0.891 seconds.”

After the above error, when you check the integrity of STM file, you might encounter the below possibly misleading error:

“Operation terminated with error -1206 (JET_errDatabaseCorrupted, Non database file or corrupted db) after 0.901 seconds.”

You are highly recommended not to use Exchange Server database repair utility against problem STM file as it might damage the internal structure of STM database file. At the same time, you may receive further error message stating:

“Operation terminated with error -1601 (JET_errRecordNotFound, The key was not found) after 2.354 seconds.”

What Causes Fragmentation Errors in Exchange Server ?

The above problem may occur if any of the below conditions are true:

1. This behavior occurs because the version of Eseutil utility doesn't ensure that you're running the tool against correct Exchange Server database. Structure of STM file is different from structure of EDB file. Some Eseutil functions might damaged STM file.

2. The Exchange Server database is corrupt and Exchange Server can not read it.

Solution

Go through the below steps to fix this problem and perform Microsoft Exchange recovery:

1. Obtain latest service pack of Exchange Server.

2. Use third-party Exchange Recovery software to repair and restore the damaged Exchange Server database.

Exchange database physical corruption: Ways to detect, prevent and recover

2010-06-04T04:53:00.001-07:00

Microsoft Exchange Server is an excellent and cost-effective collaboration and communication application used by several organizations all over the world. The Exchange Server database (.edb) file serves as the repository to save mailboxes data. If this .edb file falls prey to physical corruption, you can experience serious data loss situation. To deal such cases, you must need to restore Exchange sever from a valid backup. However, if there is no backup available, you need to employ an Exchange Server Recovery utility to recover lost or inaccessible data.

Detecting physical corruption

It is quite essential for a user to identify a physical corruption scenario at an early stage and resolve the issue with proper corrective measures quickly in order to avoid disastrous data loss cases.

Information store is a key component of MS Exchange Server, having two databases viz private information store and public information store. During an event of physical corruption in the information store, you may encounter the following error, thrown by Microsoft Exchange Server:

“-1018 (JET_errReadVerifyFailure) The data read from disk is not the same as the data that was written to disk”

“-1022 (JET_errDiskIO) The hardware, device driver, or operating system is returning errors”

“510 JET_errLogWriteFail The log files are out of disk space or there is a hardware failure with the log file disk”

Though, these errors indicate the physical corruption in the information store, there is yet another way to detect the physical corruption i.e. online backups. The online backup process thoroughly checks every single page in the database. When you spot an evidence of physical corruption, it is wise to opt for an appropriate and effective Exchange Recovery Software

Preventing physical corruption

1.Make sure you use quality hardware components and configure the system correctly
2.Make sure not to run file-level utilities, like anti-virus program on a computer which is acting as an Microsoft Exchange Server
3.Turn off write-back caching. If you do use write-back caching, ensure that the data is completely protected

Recovering after physical corruption

Use backup
As told before, the only best way to deal with a physical corruption instance is by using an updated backup, so that the log files can be rolled forward to bring the system to a consistent state.

Eseutil.exe utility
You can also consider running the Eseutil.exe utility in order to perform Exchange Recovery. However, it is not very much recommended to use this utility as it deletes the damaged pages and make the broken or inconsistent database running again.

Third-party recovery software

Download a reliable third-party Exchange Recovery tool from the Internet and restore the corrupt database. This is the best and safest way to recover your .edb file.

Stellar Phoenix Mailbox Exchange Recovery repairs a corrupt Exchange Server database and restores all mailboxes as .pst files. Compatible with MS Exchange Server 2007, 2003, 2000 and 5.5, the easy-to-use tool also allows selective Exchange mailbox recovery and deleted mailbox recovery.

How to Recover Exchange Server Information Store in a Single Site ?

2010-05-24T23:23:00.000-07:00

Exchange Server is the server side application from Microsoft to create a collaborative messaging environment. It is made of various components, and Exchange Server Information Store is a significant one among them. All the database components work together to perform required operations and keep Exchange Server up. However, there are several factors that can damage the Exchange Server components and may make it unusable. This behavior renders your Exchange Server database (EDB file) inaccessible and cause severe data loss. To recover lost data at this point, you must go for Exchange Recovery solutions, if a valid backup is not available.

When Exchange Server database corruption takes place, Exchange Server Information Store is the most commonly affected components. Microsoft Exchange Server Information Store comprise of the below four database files:

1.Priv1.edb
2.Pub1.edb
3.Priv1.stm
4.Pub1.stm

Both stored and in-process non-SMTP messages are held by Priv1.edb file. SMTP messages are stored in Priv1.stm file. Public store folder for non-SMTP messages is stored in Pub1.edb file and for SMTP messages is stored in Pub1.stm. Generally the database corruption includes either of EDB files.
Exchange Server Information Store corruption is usually indicated by the below symptoms:

1.Information Store Service doesn't start.
2.You can't stop Information Store service.
3.Information Store service stops responding.
4.Exchange clients can not send or receive mails.
5.You receive the below error, if you restore Exchange Server database from offline backup, and run Isinteg.exe (Information Store Integrity Checker) utility:

“Error 4294966746: JET_errDatabaseInconsistent”

6.You come across the following error message when you attempt to Mount mailbox store in Microsoft Exchange System Manager:

“Unable to Mount the Mailbox Store with error c104173c 'The Information Store is Busy'”

Resolution

You can perform Microsoft Exchange recovery by resolving this problem, using the below steps:

1.Restore database from backup.
2.Use Exchange Server database consistency adjuster.
3.Run Exchange Directory Service Integrity Checker.
4.Merge database using ExMerge utility.

If the above methods do not work, it becomes essential to repair and restore the damaged Exchange Server database using third-party Exchange recovery software.

The applications are specifically designed to carry out in-depth scan of entire EDB file and extract all inaccessible data from it. With simple graphical user interface, the Exchange database recovery process is quite simple with these tools.

Hard Recovery Fails After Restoring Exchange Server Database From Online Backup

2010-05-19T23:38:00.000-07:00

In Microsoft Exchange Server, you are required to to perform hard recovery after restoring your database from an online backup. Hard recovery is a log replay process, which is similar to the soft recovery, however there are a few critical differences. If you do not complete the hard recovery process after restoring the database from backup, the restore process is not successful. In some situations, the hard recovery process fails and your database remains inaccessible even after restoring from an online backup. This behavior causes severe data loss and requires Exchange Server Recovery to be sorted out.

As a practical instance of this behavior, the hard recovery process may not complete successfully with eseutil /ff command after restoring Exchange Server database (EDB file) from online backup. Additionally, you receive underwritten error message:

“Operation terminated with error -939523485 (Existing log file is not contiguous.) after 0.481 seconds.”

After the above error, you see the below events in the Application Event Log of Microsoft Exchange Server:

After this behavior of Microsoft Exchange Server, the database remains inaccessible. In order to access your EDB file in such situations, you need to find out the cause of this problem and then perform Exchange Server recovery by resolving it.

Cause

The above problem occurs if old log files are not in sequence with log, which is described in the Restore.env file. You can list out the required log files using eseutil /mh utility.

Resolution

To sort out this behavior, you need to repair and restore damaged EDB file using Exchange recovery software. These software use high-end scanning techniques to scan entire database and extract all mailboxes from it. With graphical user interface and non-destructive conduct, the Exchange recovery tools are totally easy and safe to use.

Repairing oversized corrupt EDB file in MS Exchange Server 2003

2010-05-18T01:47:00.000-07:00

Microsoft Exchange Server is the server-side of the client-server product by Microsoft. It provides support for emailing, calendar entries and mobile- and web-based access to exchange information. All such information is stored in an EDB (Exchange Information Store Database) file. However, sometimes the EDB file can get corrupt due to which you are unable to mount the mailbox. Corruption situations can arise due to various reasons such as virus infections, human errors, database header corruption, quitting Exchange server unexpectedly, etc. In such cases, you should take appropriate corrective measures to rectify the situation. However, if you are unable to do so, then you should use a third-party Exchange Repair software to do the needful.

Consider a scenario wherein you are not able to mount Microsoft Exchange Server 2003 Standard Edition mailbox. The event ID is logged in the Application Event Log:

“Event Type: Error
Event Source: MSExchangeIS
Event Category: General
Event ID: 1112
Description: The database "Mailbox Store (Server Name)" has reached the maximum allowed size. Attempting to unmount the database.”

Cause:

The cause of this erroneous situation is that the EDB file has corrupted as its size has exceeded the permissible size of 16 GB.

Resolution:

To resolve the situation:

1. Upgrade to Exchange Server 2003 SP2 as it has got size limit of 75 GB.

2. Perform the following tasks if you are an administrator:
     a)Increase the database size limit temporarily by 1 GB.
     b)Remove the not so required database content.
     c)Defragment the database to reduce it to the permissible database size limit.

3. Mount the database in a recovery storage group by using the Recovery Storage Group feature. Then, you can use the MS Exchange Merge Wizard (Exmerge.exe) to extract the mailboxes from the database.

However, if you still are unable to resolve this issue then you should use a third-party Exchange repair software to repair the EDB file. Such tools are able to repair the EDB file without overwriting the original contents and by using fast yet sophisticated scanning algorithms.

Stellar Phoenix Mailbox Exchange Recovery is an MS Exchange repair software that enables you to repair corrupt EDB files. It scans the corrupted EDB file, repairs it, and saves it at a user-specified location. This Exchange repair software recovers different mailboxes in a separate PST files.

Error C106fdda - MS Exchange Server Upgrade Fails

2010-04-29T02:22:00.000-07:00

Microsoft Exchange Server version upgrade is the practice followed for keeping the server up-to-date, secure, and more reliable. The process involves upgrading Exchange Server databases, which includes the Priv.edb and Pub.edb- the essential data storage components of Exchange Server. If the upgrade process fails on any of these database files, then that database might be inconsistent. This usually occurs because of an ungraceful shutdown and requires specific EDB Recovery solutions.

Here is an example illustrating how an upgrade process can fail in MS Exchange Server. Let's say, you try to upgrade to Exchange Server and the process fails. On each attempt of doing so, you receive the below mentioned error message:

“An unexpected error has occurred.
ID No. c106fdda”

This error won't allow you to upgrade Microsoft Exchange Server. However, if you apply a fault-tolerant setup, the given error pops up:

“Your upgrade did not complete successfully. Please restart your Microsoft Exchange services and your system will behave as it did before the upgrade was attempted.”

Such problems specifically occur when Exchange Server setup during upgrade finds a database that is not consistent. Since an inconsistent database cannot be upgraded, the setup exits with a failure error message, as above.

User Action

If you encounter the problem that has been discussed above, you need to perform the below sequence of steps:

Quit the Exchange setup program
If you didn't choose the fault-tolerant upgrade at start, you need to check the consistency of all databases using commands as follows:

drive:\Winnt\System32\eseutil /mh file_path\priv.edb
drive:\Winnt\System32\eseutil /mh file_path\pub.edb

However, in case the fault-tolerant upgrade was chosen. The following commands will help:

drive:\exchsrvr\bin\edbeutil /mh file_path\priv.edb
drive:\exchsrvr\bin\edbeutil /mh file_path\pub.edb

Execute the below mentioned command for the inconsistent database:

:\Winnt\System32\eseutil /r /ispriv
:\Winnt\System32\eseutil /r /ispub

If the database doesn't become consistent again, you should restore it from the last available backup or run a third-party EDB Recovery Tool. An EDB Recovery software can scan a corrupted Exchange database file and extract its data in readable form, accessible by normal means.

Stellar Phoenix Mailbox Exchange Recovery is a comprehensive solution designed for repairing a corrupted Exchange EDB file and restoring the mailboxes as *.pst files. This EDB Recovery Tool supports MS Exchange Server 5.5, 2000, and 2003 and provides advanced options to aid recovery. In addition, it can also recover deleted mailboxes.

Resolving Event ID 489 in Exchange Server

2010-04-08T23:36:00.000-07:00

Microsoft Exchange Server database file can often develop errors, which it finds unable to remove by normal repair methods. Inability to open a database file is one such error. An Exchange Recovery Tool comes handy when your Exchange database becomes corrupted and you have no backup to restore.

The further discussion depicts a commonly occurring problem when trying to open an Exchange database file. In such situations, you can encounter unexpected error and file open operation might fail. On viewing the application event log, you may observe the below event log:

Event Type: Error
Event Source: ESE
Event Category: General
Event ID: 489
Computer:Computer Name
Description: Process name [process id] file name: An attempt to open the file [path\file name] for read-only access failed with [Error Code and Explanation]. The open file operation will fail with error [Error Code].

Cause and Resolution

The actual cause of event 489 can be determined by the error code ('error_code') displaying at the end of its 'Description' section. Below are the possibly occurring error codes along with their causes and solutions:

Error -1032= ' JET_errFileAccessDenied'= File cannot be accessed

The file is in use by some other process or utility like, a virus checker or a backup program. Another cause can be insufficient permissions on folder containing database files to let the store to function correctly.

Thus, you need to configure the program using the database file to not scan the Exchange Server directories and/or to change the folder permissions to the default ones.

Error -1022='JET_errDiskIO' = Disk I/O error

The requested database page cannot be accessed due to an I/O error. It could be because of disk or controller failure or because the path to check file is incorrect.

You should run chkdsk /f /r command, check valid permissions on Exchsrvr folder, ensure the correct path to check file, and troubleshoot file-level anti-virus software scanning. After this, you need to either restore the database from backup or repair the database using Exchange Recovery Tool- eseutil/p, isinteg -fix, and ExMerge.

Error -1023= 'JET_errInvalidPath' = Invalid file path

Possible causes are changed path to log files or check files before restoring and corrupted check files or temporary files created while a defragmentation or a repair.

Therefore, you need to place back the files to their original locations and remove the corrupted files. To correct database inconsistency, you need to either restore the database from backup or repair the database using eseutil/p, isinteg -fix, and ExMerge tools.

Exchange repair utilities can delete the corrupted pages. For safe repair, use of Exchange Recovery Software is recommended.

Stellar Phoenix Mailbox Exchange Recovery is a reliable utility that is used to repair corrupted Exchange database and restore its mailboxes as *.pst files at a safe location. This Exchange Server Recovery software supports MS Exchange Server 2007, 2003, 2000, and 5.5 and can also recover deleted mailboxes.

Tips To Resolve “Operation terminated with error...” Error Message

2010-04-04T22:15:00.000-07:00

Eseutil/p is an inbuilt repair utility of MS Exchange Server that repairs corrupted Exchange Server databases at both table and page level. While the repair utility proves successful in repairing most of the corrupted databases, there are certain situations wherein the command fails to repair a corrupt database. In such situations, it displays an error message. This happens when the database is severely damaged. Since the database cannot be repaired, it remains corrupt, and the data saved in it remains inaccessible. To access database in such situations, a user needs to restore database from a previous online backup. However, in the absence of an updated backup, a user needs to repair the database using a third-party Exchange Server Repair application.

For detailed explanation of the above problem, consider a practical case wherein your Exchange Server database gets corrupted. And, when you try to repair the database using Eseutil/p utility, you encounter:

“Operation terminated with error -1605 (JET_errKeyDuplicate, Illegal duplicate key) after xxx.xxx seconds.”

Data saved in the database becomes inaccessible after the above error message appears. Additionally, the same error message repeatedly occurs when you try to repair your database.

Cause:

The fundamental reason for the occurrence of the above error message is that the repair utility might rebuild B-trees incorrectly. This will change the complete metadata structure of the database, leaving it in a permanently non-repairable state.

Resolution:

To resolve the above error message and to access the records saved in the database, a user needs to obtain the latest service pack of MS Exchange Server 5.5 and perform repair. However, if the repair utility is unable to repair the database even after installing the service pack, then you need to opt for an advanced commercial Exchange Server Repair application.

An Exchange Repair software is a powerful utility specifically designed to repair MS Exchange database, that has become corrupted due to logical crash. The read only utility performs repair without making any change in the original database file.

A) You get Event ID 7011 while working on Exchange Server.

B) The SMTP (Simple Mail Transfer Protocol) service on Exchange Server computer stops responding or terminates improperly.

C) System freezes when you run - IISADMIN, W3SVC, IMAP4SVC, RESVC, and POP3SVC services. You need to restart your computer when it occurs.

D) The services fail to stop when you try to stop and restart them.

E) You may encounter error messages, similar to the followings:

i. Timeout (30000 milliseconds) waiting for a transaction response from the RESVC service.
ii. Timeout (30000 milliseconds) waiting for a transaction response from the IISADMIN service.
iii. Timeout (30000 milliseconds) waiting for a transaction response from the W3SVC service.

This behavior of Microsoft Exchange Server renders your valuable data inaccessible. In order to get your Exchange Server data back, you need to first identify the root cause of this problem and then fix it with Microsoft Exchange Recovery.

Grounds of the issue

You may come across this behavior of Microsoft Exchange Server due to any of the below reasons:

1. A message is received by the MS Exchange Server 2000 system, which has a damaged time stamp.

2. The message has an invalid FILETIME attribute.

3. Exchange Server database is corrupted due virus infection, improper system shutdown, and application crash situations.

Resolution

Information Store Corruption due to RAID Issues

2010-03-10T22:03:00.000-08:00

One of the common reasons for Exchange Information Store to get corrupt is hardware issues. Thus when you identify server consolidation for Exchange Server computer, experts suggest you to adhere to Windows Server Catalog tips. The most important is a reliable storage subsystem and that's the reason you are often recommended to use Redundant Array of independent Disk (RAID) configuration. This not only increases performance by allowing multiple I/O operations but also adds to reliability. But unfortunately there can still be instances that may bring corruption to message store. If one or more of RAID components fail, the Exchange Information Store can catch corruption. In such situation, you need an Exchange Recovery solution to repair the database and recover the lost data.

Consider you use a RAID 2 system to run Exchange Server. All the Information store data including the log files are stored on the same drive. You observe that one of the RAID drives shows typical corruption issues. So you replace the drive, but you experience similar kind of problems with other drives as well.

Later, you notice that you cannot mount the Information Store. When you run eseutil /mh command to check the integrity of the database, it shows that Information store is corrupted. The database files and log files (typically, e00.log file) are damaged.

Cause

Since disk issues are repeatedly observed, it indicates issues with the RAID controller that has ultimately corrupted the Information Store database files.

Solution

You need the following solutions to deal with such problems:

Run eseutil /p command to repair the corrupted database. Keep in mind that this can delete the corrupted pages, so to prevent against critical data loss, it is recommended to use the command on a database backup.
Restore from a valid backup. But it is likely that database backup may also not exist in usable state. The reason is that the corruption problems have been continuous for considerable time and it is possible that you might have backed up the corrupted Information Store.
Use a third-party Exchange Recovery utility. The Exchange Server Recovery software can scan and then repair the corrupted Exchange database using powerful, yet safe, algorithms.

Exchange Server Recovery Softwareis a reliable tool that repairs corrupted Exchange database and extracts mailboxes as *.pst files while keeping the original database unaffected. The Exchange Recovery Tool supports MS Exchange Server 2007, 2003, 2000, and 5.5. The tool can also recover deleted mailboxes.

EDB Recovery to Fix Transport Database Corruption

2010-02-24T20:25:00.000-08:00

Are you facing fatal errors while accessing your Microsoft Exchange Server 2007 database? Is your EDB (Exchange Server Database) file is inaccessible? The fatal error in Exchange server aborts the application and thus makes it unusable. This behavior of MS Exchange Server renders all your valuable data inaccessible and cause critical data loss situations. In order to get your precious data recovered in such situations, you need to repair and restore the damaged EDB file, using an EDB Recovery solutions.

As an example, MS Exchange Server 2007 Management Pack for Operations Manager supervises the MS Windows Application Event log on systems, which are running MS Exchange Server 2007 and returns the below event:

“Product Name: Exchange
Product Version: 8.0 (Exchange Server 2007)
Event ID: 17003
Event Source: MSExchangeTransport
Alert Type: Critical Error
Description: A Transport database operation has encountered a fatal error. The database may be corrupted. The Microsoft Exchange Transport service is shutting down. Manual database recovery or repair may be required.”

After the above error, Microsoft Exchange Server does not let you access your database. At this point, you have to verify the cause of this problem and perform EDB File Recovery by resolving it.

Cause:

The error message below indicates that specified ESE (Extensible Storage Engine) database is damaged. It is preventing MS Exchange Server services from starting.

- ESE, also called JET Blue, is an ISAM (Indexed Sequential Access Method) data storage technology intended by Microsoft. The ESE is particularly used as a key component of the Microsoft Exchange Server and the Active Directory.

How to Fix ESE Corruption:

You can carry out following things to sort out this issue-

Delete the defined database and corresponding transaction logs. You must not remove the database if you have significant data in the database.
Repair the damaged database using Isinteg.exe tool or restore it from backup.

However, if none of the above methods helps you to work around the problem, EDB Recovery Tool is the only option to go for. They carry out in-depth scan of entire EDB file using high-end scanning techniques and restore all database objects such as emails, notes, contacts, tasks, and more.

The software enable you to recover corrupt EDB file in a quick and easy way as they are incorporated with simple and self-descriptive graphical user interface. The integrity of your database is always preserved by these tools.

EDB Recovery Software is the most preferred recover EDB solution to repair and restore EDB files in all cases of corruption. The EDB Recovery is designed for Microsoft Exchange Server 2007, 2003, 2000, and 5.5.

Tips to Solve - Error 4294966746: JET_errDatabaseInconsistent in MS Exchange Server

2010-02-22T21:02:00.000-08:00

An Exchange Server database is susceptible to different corruption problems, such as dirty database shutdown, antivirus scanning, log file issues, and others. Thus an administrator might require different Microsoft Exchange Recovery tools to solve such problems and to continue working the e-mailing environment.

Further is a scenario that depicts a similar situation of Exchange Server database corruption. As an Exchange Server administrator, you may observe one or more of the below symptoms:

You cannot start and/or Information Store service
Exchange clients lose the ability to send or receive e-mails. You cannot solve this issue by restarting the server
You restore the database from an offline backup but the database is still inconsistent. On running Isinteg utility (database integrity check), it gives the below error message on screen:

“Error 4294966746: JET_errDatabaseInconsistent”

Cause

Information Store is corrupt. Either both or one of public store and private store is corrupted.

Solution

Before trying the below steps, you are recommended to take the backup of the entire Information Store to prevent any post-crash consequences. Use the below steps in order to solve the above problem:

Analyze all the error message and events of application event log that Exchange reports on attempting to start the Information Store
Run eseutil /mh command to check the integrity of Exchange databases (Priv.edb and Pub.edb). An inconsistent database shows 'Dirty Shutdown' state but is not always corrupt. This state can also occur if all the transaction logs have not been committed yet.
Replay all the transaction log by performing soft database recovery. For this, execute eseutil /r command for the affected database(s).
Run hard database repair in case soft recovery doesn't work. Run eseutil/ p command and delete all the .chk and .log files
Check if the previously occurring symptoms go away. If you can successfully work with the database(s), they are repaired. Next, run eseutil /d and isinteg -pri -fix -test alltests commands in sequence to defragment and fix database issues respectively.
In case, the problem remains the same, use a third-party Exchange Server Recovery tool to diagnose and repair the database more effectively. A Microsoft Exchange Recovery utility uses safe, yet powerful, scanning procedures and allows for easy database repair.

Exchange Recovery Tool is a professional utility that repairs corrupted Exchange database and extracts the mailboxes in individual *.pst files for Exchange Server 2007, 2003, 2000, and 5.5. The tool provides advanced Exchange Recovery features and is easy to use. It can also recover deleted mailboxes and inaccessible STM data.

Fixing Error Message Post Information Store Corruption

2010-02-19T20:20:00.000-08:00

Information Store is one ost vital components of Microsoft Exchange Server that stores transaction logs and database files. Unlike any other database corruption, Information Store databases can also get corrupted due to dirty database shutdown, anti-virus scanning, and log file corruption. In most of these situations, you encounter an error message that suggests database corruption. To easily overcome such database corruption scenarios, you need to restore the data from an online backup. But in case of online backup unavailability, you will need to opt for advanced Exchange Server Repair solutions.

To illustrate the above case, consider a scenario where you attempt to take a backup from Veritas software and you encounter the below error message:

"Access Denied to Database Mailbox Store (Server Name) - Warning mailbox
Store (Server Name) is a corrupt file. This file cannot verify"

After the above error message pops up, the database backup process stops. On viewing the application error log, you view event id 217. The description section for the same event is mentioned underneath:

“Information Store (2320) 8d59bacd-96a8-4d3a-b1cd-0f31dc7be0b8: Error (-613)
during backup of a database (file D:\ProgramFiles\Exchsrvr\mdbdata\priv1.stm). The database will be unable to restore. Information Store (3272) The streaming page read from the file "D:\ProgramFiles\Exchsrvr\mdbdata\priv1.stm" at offset 5598494720 (0x000000014db24000) for 4096 (0x00001000) bytes failed verification due to a page checksum mismatch. The expected checksum was 3969232578 (0xec95aec2) and the actual checksum was 4119053255 (0xf583c3c7). The read operation will fail with error -613 (0xfffffd9b). If this condition persists then please restore the database from a previous backup.”

Cause:

The fundamental cause for the above error message is corruption of database.

Resolution:

To resolve the above error message, you need to:

Restore the data from an updated backup, as suggested in the error log.
Run Eseutil/d (offline defragmentation) to resolve minor corruptions in Microsoft Exchange database.
Run Eseutil /p and then run Isinteg -fix to fix corruption on a database backup.

However, if the problem still persists, then you need to go for an advanced Exchange Repair to extract user mailboxes from the corrupted database. Such Exchange Server Repair solutions can be easily downloaded from the Internet and used even by a novice user.

MS Exchange Repair is a advanced EDB repair application that repairs corrupt Exchange EDB file, irrespective of its cause of corruption. The repaired mailboxes can be saved in separate *.pst files. With recovery of deleted mailboxes, the Exchange Repair software supports Exchange Server 5.5, 2000, 2003, and 2007.

How to Resolve - The private store could not be updated - Exchange Server Error

2010-02-18T01:16:00.000-08:00

In Microsoft Exchange Server, you can check and fix the integrity and consistency of Information Store database using Isinteg.exe utility. This built-in command-line tool works on all information store databases such as public information store, Pub.edb, and private information stored, Priv.edb. However, in some cases, you encounter errors while trying to resolving information stored database issues in Exchange Server, and the process fails. The problem persists and you can not access data from Exchange Server database. This behavior leads to data loss and need Exchange Server Recovery to be sorted out.

In a practical scenario, you may come across the below error message when you run the Isinteg -patch on MS Exchange Server that is running on Microsoft Cluster Server:

"The private store could not be updated
Reason: JET_errKeyDuplicate"

Before running the Isinteg -patch tool on Microsoft Exchange Server computer, which is running on the Microsoft Cluster Server, it is essential to set environment variable _CLUSTER_NETWORK_NAME_ to ERG
(Exchange Resource Group) name. For instance, when the ERG network is named as EXCLUSTER, type the below as command prompt:

SET_CLUSTER_NETWORK_NAME_=

The failure occurs if the value of _CLUSTER_NETWORK_NAME_ environment variable is incorrect. It can be due to typographical errors. After the environment variable is set, you can not change it.

If you have incorrectly set the environment variable on your Exchange Server database, the database corruption or inaccessibility situations may occur. In such circumstances, you must perform complete restore of the database as you can not change cluster name in information.

Inaccessibility of the Exchange Server Database (EDB) file leads to data loss situations and need Exchange Recovery to be sorted out. Recovery is best possible with the help of powerful and advanced third-party EDB Recovery Software.

These applications are particularly designed to carry out in-depth scan of entire EDB file and extract all damaged, inaccessible, and corrupted mailboxes. The Exchange Server Recovery tools have read-only and non-destructive conduct to retrieve your data safely.

Microsoft Exchange Recovery is a comprehensive edb recovery tool and ensure absolute recovery of all EDB file objects including emails, notes, contacts, tasks, journal, and more. The software works well with Microsoft Exchange Server 2007, 2003, 2000, and 5.5.

Tips to Solve 'JET_errLogCorruptDuringHardRestore' Exchange Server Error

2010-02-15T01:00:00.000-08:00

Exchange Server database corruption can occur for several reasons and if backup is present that is stable, you can use it to restore the database conveniently. A database backup alone is not sufficient to bring the database back to consistent state. It is because after restoration, database and log files are not in perfect sync with each other. So, you need to replay the transaction files in order to make the database consistent. This process is termed as 'Hard Recovery'. The hard restore requires all backup sets to be in clean state or otherwise, this procedure may fail. In such instances, you left with no alternatives other than using an Exchange Server Recovery utility that can repair the original database.

As example, consider an instance when you experience dirty shutdown with Microsoft Exchange Server. The next time, when you try to mount the Information Store database(s), it fails and you receive errors suggesting that one or more database(s) are corrupt. You try to perform hard restore, but cannot do so and receive the below error message:

“JET_errLogCorruptDuringHardRestore -573”

The database recovery method fails and data remains inaccessible.

Cause

Error -573 indicates that Exchange Server has detected some corruption in a backup set and cannot proceed.

Solution

You can try applying these solutions to solve such problems:

Check for some other backup set that may be used to restore the database and carry out hard restore
Run 'ESEUTIL /P database_filename.edb' command to repair the database, where 'database_filename' is the name of the corrupted database file. But during repair, the command can discard table rows and even complete tables. So, it is suggested to backup the database and later, opt for safe third-party Exchange Server Recovery solutions if you find the important data missing after repair or the repair process fails.

Exchange Recovery software are result-oriented tools to that repair corrupted Exchange Server (EDB) files using safe and effective scanning algorithms. These products are applicable in each case of database corruption. You can install these products easily and then operate them using simple steps as described by the software itself.

Microsoft Exchange Recovery is a powerful utility that repairs corrupted Exchange database files and restores the mailboxes in individual *.pst files. The Exchange Recovery tool supports MS Exchange Server 5.5, 2000, 2003, and 2007. The tool can also recover deleted mailboxes. The software is compatible with Windows 7, Vista, XP, 2003, and 2000.

A corrupted or damaged Exchange Server database exhibits abrupt behavior while normal database operations. However, you can deduce the root cause of the issue and sometimes, solution to the problem by application log entries. You should restore the corrupted database from the last backup, if is available and valid. In case of database issues, you are recommended to use EDB Recovery Software to recover the damaged database.
For example, consider you use Exchange Server 2003 or Exchange Server 2000. You use Exchange online backup to backup your Information Store database and fail to do so. When you view the application log in Event Viewer, you encounter the below error message:

“Information Store (2240) The database page read from the file "E:\program files\exchsrvr\mdbdata\priv1.edb" at offset 204275712 (0x000000000c2d0000) for 4096 (0x00001000) bytes failed verification due to a page checksum mismatch. The expected checksum was 303571876 (0x121823a4) and the actual checksum was 303571940 (0x121823e4). The read operation will fail with error -1018 (0xfffffc06). If this condition persists then please restore the database from a previous backup.”

This error is logged with event ID 474.

Cause

Error 1018 indicates JET_errReadVerifyFailure error. It results because of checksum errors on database pages. The prominent reason for this error to occur is Exchange database corruption due to file system errors. If the disk subsystem is suffering from issues, like defective disk drivers, faulty controller or outdated or incompatible firmware, this could result into Exchange database corruption.

Solution

You can solve these problems by these methods:

1.Try to perform backup using different storage group located on a different server disk. 2.Diagnose and troubleshoot your Exchange Server running system for possible hardware issues
3.Update your system with the latest firmware and drivers updates available
4.If a clean data backup is available, restore your database
5.Perform hard repair of the database using Eseutil /p in case no suitable backup is present 6.Eseutil /p is a destructive repair operation that could delete the corrupted database pages. To prevent the consequences, you should use safe EDB Recovery utilities.

EDB Recovery Software are powerful tools to examine, repair and restore damaged Exchange databases using efficient scanning algorithms. These tools provide you graphically rich user interface and advanced features that result complete database repair.

Exchange Database Corruption after Installing SP2

2010-02-15T00:52:00.000-08:00

Microsoft Exchange Server 2003 SP2 offers new features, more reliability and easier administration over its earlier counterparts. SP2 is a cumulative update that improves the Exchange messaging environment by including improvements in mobile messaging, mailbox and protection against spam. Before you upgrade your servers to Exchange Server SP2, it is recommended that you make complete backup of system state, file system and most importantly, Exchange databases. This assures of data availability in case the installation goes wrong in any way. But cases occur when your Exchange databases get corrupt when no clean backup is present. In such situations, you should use a powerful Exchange Server Repair product that can use safe scanning algorithms to repair a corrupted Exchange database.

For instance, you can consider a scenario describes below:

1. You run Exchange Server 2003 SP1 or an earlier version
2. You decide to upgrade to Exchange Server 2003 SP2. During the installation of SP2, the setup failed to stop ExIFS (Exchange Installable File System) service but continues with no notice
3. After this, when you try to mount Information Store, it fails and events 470, 9519, 9518 and 104 are logged in the application log.

Cause

The above symtoms suggest that Exchange database may have got corrupted due to installation of SP2. It can also occur if an antivirus software is scanning the Exchange databases. Solution Before making any database restoration attempts, you should make sure that Exchange databases are excluded from any antivirus scanning.

If databases appear as corrupted, you should consider these suggestions:

1.Try repairing the corrupted database by running eseutil /r command

2. If it fails, restore the database from the last backup you have

3. When no clean backup is available, you should use a Exchange Repair software.

Solving Exchange Server 2007 Database Corruption ?

2010-02-05T22:18:00.000-08:00

Microsoft Exchange Server 2007 includes several data security and database improvements that give an appearance of a relatively safer application. The prime enhancements that this version provides are extended database size limitation up to 16 TB, increased number of storage groups per server, improved antivirus, anti-spam protection, and more. Despite of these improvements, Exchange database corruption is not an exception. An Exchange Server 2007 database is vulnerable to get corrupt because of Dirty shutdown, application issues, and the like common causes. The prime solution to deal with such problems should be use Exchange repair utilities or to restore from backup. But if none of these measures works, you require an Exchange Recovery utility.

Consider the following practical example of such problems. You use Exchange Server 2007 and observe database corruption with the following symptoms:

You try to copy the database, but the copy operation fails reporting an I/O error in system log, such as below:

The driver detected a controller error on \Device\Harddisk0\DR0.

When you try to move a mailbox from the corrupted store to a new one, it cannot be accomplished with an error similar to below:

Unable to move mailbox mailbox_name.
A problem occurred while getting the properties for a message.
Parent folder name: Inbox; Message subject: RE: SND253P1 ; Error code: 0xfffffa0a.
Run ISINTEG to check for any problem in the database "First Storage Group\Mailbox Database

As suggested by the above error, when you run ISINTEG utility to check the database consistency, you receive the below error:

MSExchangeIS (3932) First Storage Group: Data inconsistency detected in table table_num of database database_path

Also, the ESEUTIL /p repair operation fails to fix the database corruption.

Such situations indicate database corruption to an extent that it cannot be repaired and dealt using MS Exchange utilities. To extract the mailboxes, you need solutions like:

1. A database backup that can be used to restore.

2. A third-party repair Exchange Server Recovery utility that can repair and restore the database contents. An Exchange Recovery utility can use effective, yet safe, scanning algorithms to recover the lost data in intact form.

Exchange Recovery Tool is a professional utility with ability to recover mailboxes from a corrupted Exchange database in individual *.pst files. The Exchange Server Recovery application supports Exchange Server 2007, 2003, 2000, and 5.5. The tool also supports recovering deleted mailboxes and STM file data in an e-mail body.

How to Solve Table Index Corruption in Exchange Server?

2010-02-03T04:24:00.000-08:00

The main repository of mailbox data in Exchange Server is the .edb file that is primarily composed of b-trees. Since a b-tree is allowed to have a considerable depth, b-trees deploy indexes to permit quick data access. In Exchange EDB, there are few ancillary trees that hold table indexes to work with the main tree. If these indexes go corrupted, the entire table and sometimes, the whole database become unusable. This is what we refer as logical database corruption. In critical situations, when this type of corruption is not limited to index page corruption, you need to implement Exchange Server Repair solutions.

To understand such potential problems with Exchange database further, consider the discussed scenario and error. When using Exchange Server 2007, you can encounter event 467 logging in the application log. Additionally, on viewing the description section of the same event, you receive an error that reads similar to below:

Information Store (number) Index [index name] of table [table name] is corrupted.

This error typically indicates a corrupted index in the Exchange store. As symptoms, you might observe access violations and repeated crashes. Also, this type of corruption might go undetected for long without any symptoms. Even the Exchange-aware backup may fail to detect this corruption. Event 467 suggests logical corruption at Database (JET database engine) level and is exhibited when JET engine touches this location in the database while reporting it as event 447. For specific root causes, one needs to view the application and system log cautiously as these errors can damage your data badly.

Solution

Following suggestions can help you isolate the depicted problem:

1. If corruption is limited to index leaf pages and not with the database pages, running Eseutil /d (offline defragmentation) alone can perform Exchange Server Repair.

2. In critical problems, you may need to use ExMerge utility to move the mailboxes to a new, blank Information Store.

3. The Exchange Server might be affected from page or database level corruption together with index page corruption. In such cases, you can execute Eseutil /p and then Isinteg -fix commands as Eseutil /d command may not work. You can further use ExMerge tool to put the database again in use.

4. To avoid data loss problems due to Eseutil /p utility, it is however, recommended to opt for a safe third-party Exchange Repair utility.

The Exchange Repair is a professional utility that repairs corrupted Exchange EDB file and restores the mailboxes in separate *.pst files. The EDB Repair product is easy to use with its self-explanatory interface. Designed for Exchange Server 5.5, 2000, 2003, and 2007, the tool is also competent to recover deleted mailboxes.

Resolving - Database recovery and restore failed with an unexpected error - Exchange Server Error

2010-01-29T22:37:00.000-08:00

When you perform operations like an online backup or defragmentation, the system reads each database page for writing or other processes. To do so, it first undergoes checksum test and check if it is correct. For any reason, if the page checksum mismatch with that has been calculated by database engine, it reports an error and the operation is halted. Such errors usually root from physical database corruption and compel you to restore the database from backup or apply some Exchange Repair measures to fix database corruption.

As an example of such problems, with Exchange Server 2007, you might exhibit the following symptoms:

The client computer cannot start Microsoft Outlook
Users fail to send/receive e-mails
Online backups and defragmentation fail with a -1018 checksum mismatch error
The application event log in Exchange Server reports an error as below:

“Database recovery and restore failed with an unexpected error.”

Cause

The above symptoms suggest that Exchange Server has failed to read database page due to checksum mismatch and the page is corrupt. However, the same issues can also occur due to firmware malfunction or problem in RAM. For the specific reason, you are suggested to view error code that is listed in the event description.

Solution

You need to apply these measures to solve the given problem:

If the error listed in event description is -515, the transaction log file(s) might be missing. Determine the missing logs and move them back to the log directory and/or restore the database from backup.
Check the system for hardware issues and solve them or migrate to a different hardware
Consider upgrading the BIOS and firmware
Perform Exchange Server Repair with eseutil /P command, followed by eseutil /D and isinteg -fix. Make sure you backup the database first as running this repair can cause important database pages to delete.

For safer MS Exchange Repair, consider using solutions like an Exchange Server recovery software. These commercial applications are built with advanced technology to run effective scan for a corrupted database and extract the valuable data out of it.

MS Exchange Repair Software is a professional utility that repairs corrupted Exchange Server databases. The Exchange Server Repair tool recovers all the mailboxes in individual *.pst files and also allows to select them as required. The tool supports Exchange Server 5.5, 2000, 2003, and 2007. The software can also recover deleted mailboxes.

Resolving Exchange Error: “Database requires log files that could not be located.”

2010-01-16T04:05:00.000-08:00

Transaction logging is a disaster recovery procedure of Microsoft Exchange Server that helps the database to get restored in consistent state after any unexpected stop. When the database stops suddenly, it goes to inconsistent state. On next restart, Exchange Server locates and then scans the log files to apply them from the database file. But for any reason if it fails to locate those log files, the recovery attempts fail. This forces you to locate the missing log files manually. However, if it cannot be accomplished, you need to restore the database from a suitable backup or perform Exchange Server Recovery using appropriate database repair procedures.

For each event in Exchange Server, the application logs the associated entry in Windows Application log. So, you might encounter the following error message displaying in this application log, usually after unexpected stop:

"Database requires log files that could not be located. The database requires log files to continue. Make sure the log files exist. Check Event logs for more information."

The event ID of this error in 453 and can cause database to become unmountable.

Cause

Exchange database needs some log files that it could not locate to continue. For further information on which log files could not be located, you can see the event description which mentions the sequence of log files that it could not locate. It also includes the log file number, up to which recovery has been possible.

Some prime reasons that might prevent log files from being located are:
1. The temporary folder doesn't contain the log files. The transaction logs are missing.

2. An anti virus software is running that has quarantined the log file 3. A hardware failure that has caused log files to lose.

Solution

You need to apply these measures to solve the existing problem:

1. Check if the required log files have been moved. If yes, move them back to the correct folder. But if they have been deleted, you need to restore from the backup.

2. You need to stop the antivirus scanning if any and examine its registry settings to put back the current log files to correct folder.

3. If none of the above measures work, you should restore the database from the backup or apply eseutil repair (hard recovery) utilities to repair the database. Eseutil hard recovery is not safe to use as it deletes the corrupted pages. Thus, you are suggested to use commercial Exchange Recovery utilities as a better option. The Exchange Recovery software are suitable choice to repair corrupted Exchange database using safe, yet effective, scanning algorithms.

Exchange Recovery Software is a powerful EDB Recovery tool that repairs corrupted Exchange database and restores the mailboxes in *.pst files. The Microsoft Exchange Recovery tool supports MS Exchange Server 5.5, 2000, and 2003. The software is easy to install and operable using simple steps that even a non-tech user can understand.

Inconsistent Database Backup when Exchange Server is Running

2010-01-13T23:00:00.000-08:00

Exchange Server databases are consisted of .edb files (database files) and .log files (database logs). All the transactions that occur for Exchange databases are first written to .log files before actually been written to database files. A database is inconsistent if all transaction log files have not been committed to the database files. But if you shut down the information service, Exchange writes all the log files to .edb files and the database comes to a completely consistent state. Thus, if you backup the database while information service is running, it will not be consistent. If your EDB files become corrupt and you try to restore from such a backup, it will give errors and the information service might fail to start. This creates an unavoidable situations of using an EDB Repair solution for your corrupted database files.

For example, consider your Exchange database files are corrupted. When you try to start Exchange Server services after restoring from a backup, you may encounter the below error in application log or on screen:

“Error -550 has occurred”

You cannot start the Exchange Server services.

Cause

You have used the backup software when Exchange Server was online. As a result, the backup is inconsistent and has failed to perform successful restore.

Solution

To prevent such errors from occurring, you are suggested to perform the database backup after stopping all the directory and information store services. Alternatively, you can look for backup solutions that are exclusively built to perform Exchange databases' backup in online state.

However, to recover the data from corrupted database files, you need to use these tools:

1. Eseutil /r command to perform soft database recovery
2. Eseutil /p command for hard repair
3. Third-party EDB Repair Tool

The hard recovery option of Exchange deletes the corrupted pages, which is not safe. Thus, you should use EDB Repair utilities if soft recovery fails. These software bring you the most effective and safe scanning algorithms for repairing damaged Exchange databases. Due to the interactive user interface they provide, these applications are easy to implement

EDB Repair Software is a feature-rich utility that employs powerful scanning algorithms to repair a damaged Exchange database. It supports Exchange Server 5.5, 2000 and 2003. It is a safe and advanced EDB Repair Tool with impressive set of features. The tool extracts user mailboxes in individual .pst file format files without affecting the original contents and view.

How to Solve when Exchange Database Fails to Mount with (hr=0x80004005, ec=-528) Error?

2010-01-07T02:51:00.000-08:00

Transaction log files record all the modifications to an Exchange Server database and are crucial for the proper functioning of Exchange. If you remove a log file that has not been written to the associated database, it can bring several issues, the most common being that the database may fail to mount. You can solve this problem by removing all the log files, but you first need to check the database consistency. If it exists in inconsistent state, the solution is to restore from backup or apply an EDB Repair technique.

For instance, consider a scenario in Exchange Server. You try to mount a mailbox store, but the operation fails with the below error message:

“Exchange is unable to mount the database thay you specified. Specified database: Servername\First Storage Group\Mailbox Database; Error code: mapiExceptionCallFailed: Unabble to mount database. (hr=0x80004005, ec=-528)”

The error occurs each time when you try to mount the store. As a result, all the clients connected to server are disconnected.

Cause

The above error can occur if you remove a (or more) log file, which has not been committed to the database yet.

Solution

To solve this issue, you need to move the transaction log files to a different folder. For this, follow the steps mentioned underneath:

1. Stop Information Store and all databases in the storage group

2. Verify the integrity of database by running esesutil /mh command, followed by database name (for example, for Mailbox Store1 database, name is Mailbox Store1.edb). Examine the 'State' value under its header information

3. If the database is in Clean Shutdown (Consistent) state, you can safely remove all the transaction log file and save them to a different folder. Make sure you don't remove the current transaction log file

4. If the database is in Dirty Shutdown (Inconsistent) state, restore from the last online backup. In case backup is invalid, run eseutil /r command for soft recovery.

If this fails, you can run eseutil /p command for hard recovery or use an Exchange repair software. The former option (hard recovery) causes data loss as it deletes the corrupted pages. An EDB Repair utility can safely repair a corrupted Exchange database and provides secure data restoration.

Stellar Phoenix Mailbox Exchange Recovery is a powerful EDB Repair Tool that repairs and restores Exchange database created with Exchange Server 5.5, 2000, 2003, 2007 and 2010.

Cannot Mount Exchange Mailbox Store with Events 9175 and 455

2009-12-29T03:18:00.001-08:00

Exchange Server mailbox store is composed of user mailboxes and system mailboxes. Each mailbox store is made of two files : Priv.edb and Priv.stm. When a disaster occurs to any mailbox store, the EDB file is considered to be the most vital component of recovery, for the reason that it contains all email messages, headers and text attachments of users' email messages. There are various Exchange Repair software available that can repair a corrupted Exchange database, in case when you don't have any valid database backup to restore.

For instance, consider a scenario when you try to mount your Exchange Server mailbox store. The mount operation might fail logging the events 9175 and 455 in application event log.

Cause

There can several possible reasons that can cause the described issue:

1.An antivirus software is running that has deleted the Exchange log files

2.You have performed soft recovery for database using eseutil /r with incorrect logfile base name

3.Mailbox store is corrupted

Solution

To solve this issue, you need to try these fixes:

1.You should ensure that antivirus software doesn't scan Exchange Server directories. It can even corrupt the database files. If the log files have been deleted, you should restore the database from backup and play through the log files. In case when no good backup is available, you need to run Exchange repair utilities for bringing the database to consistent state.

2.You need to perform soft recovery using correct log file base name, such as e00, e01, e02 or e03 .

3.If the entire mailbox store is corrupted, you should run Eseutil /r to repair it or restore from backup. However, you can also run Eseutil /p as hard recovery operation, but this causes the dirty pages to delete. So, it is recommended to use commercial Exchange Server Repair tools that can safely repair a corrupted Exchange database.

Exchange Repair Software are powerful tools that use exclusive repair algorithms, while providing graphically rich user interface.

How to Solve MAPI call “OpenMsgStore” failed Error?

2009-12-22T23:33:00.000-08:00

For Exchange Server, MAPI uses different interface methods. The OpenMsgStore is the method associated with IMAPISession interface that is used to open a message store. The method then results a reference that is passed to ImsgStore object for further access. When the method fails, the Application log of Exchange Server computer records an event that you can analyze for knowing the root cause of failure. Amongst other reasons, one possible cause of this behaviour could the corruption of message store. If this is the case, you require to run Eseutil repair utility, restore from backup or apply a mailbox recovery technique. However, you can also use an Exchange Server Recovery product in case none of these solutions seems relevant.

For instance, you may encounter the below event log description displaying in the application event log of Exchange Server computer:

The MAPI call 'OpenMsgStore' failed with the following error:

The Microsoft Exchange Server computer is not available. Either there are network problems or the Microsoft Exchange Server computer is down for maintenance. The MAPI provider failed.
Microsoft Exchange Server Information Store
ID no: 8004011d-0526-00000000

The error is logged with event ID 9175 and is specific to Exchange Server 2000 and 2003.

Cause

The above error indicates that the Information Store (IS) is not running or the mailbox store is failing to mount. If the IS doesn't run, the System Attendant still remains active with the MAPI session. The IS may stop due to any of the below possible reasons:

You are using an expired evaluation version of Exchange Server
The partition storing the IS files is less than or equal to 10 MB in size
The IS is in dirty shutdown state
The store is dismounted and/or corrupted

Solution

You should first verify if the IS is running or not. For this, go to Services and check the status of Information Store. If it is running, make sure that the mailbox store(s) are mounted and if it is not running, try to restart the store. You can try these suggestions to overcome the IS and mount failure issues:

Use the activated version of Exchange Server
Make sure that the IS partition is greater than 10 MB in size
Replay all the transaction log files for the affected mailbox store
Backup your store and run eseutil /p command to repair it. The command can delete the corrupted pages and cause data loss.

For repairing the corrupted Exchange database safely, it is recommended to use an Exchange Recoveryutility. Microsoft Exchange Recoverysoftware are scanning-based products specifically built to repair the corrupted database and restore it at a safe location.

Stellar Phoenix Mailbox Exchange Recovery is an advanced tool that repairs the corrupted Exchange database and extracts mailboxes in individual *.pst files. The powerful Exchange Recovery solution can restore all file objects using safe algorithms. The tool supports Exchange Server 5.5, 2000, and 2003.

Exchange Server 2000 and 2003 Databases Dismount due to Exhaustion of Log Files

2009-12-20T23:42:00.000-08:00

Exchange Server supports transaction logging and numbers them sequentially. It starts naming them from E nn 00001.log and goes on till E nnffff0.log, where nn represents the storage group number. When all the log files are exhausted, Exchange Server gives 'JET_errLogSequenceEnd' error and causes different issues, as discussed below. You need to remove these log files while making sure that the databases are healthy. If not, you should restore them from backup or repair using eseutil utility or a EDB Recovery Software.

For instance, you might come across these symptoms in a computer running Exchange Server 2000 or 2003:

The connected users experience failures when trying to logon to their mailboxes. The databases become inaccessible even when they are mounted. It specifically occurs in Exchange Server 2000 that is not using August 2004 Exchange 2000 Server post-Service Pack 3 update rollup or in original version of Exchange Server 2003. The application log shows event ID 1022.
The databases in computer running Exchange Server 2003 SP1 or SP2 or August 2004 Exchange 2000 Server post-Service Pack 3 update rollup get dismounted without displaying any warning. When you try to mount them, it shows an internal processing error and logs event 1159 and 9518 in application log.

Cause
Exchange Server has used all the available transaction log files of storage group.
Solution
To solve the given problem, you need to reset the log sequence by removing all the log files to a different location. But before you do so, you should ensure for databases' consistency. You should follow these steps:

Select the ' Don't mount this store at start-up' option to make sure that they don't mount at startup
Dismount the database that cannot be dismounted by killing the store
Mount the other storage groups by restarting the store
Try to repair the problematic storage group databases by running eseutil /r
Check for databases' consistency by running eseutil /mh
If they are consistent, move checkpoint and log files to a different location and mount the databases
If the databases remain inconsistent, you should delete the damaged databases provided you have a full backup to restore. If not, you can use a powerful EDB Recovery utility to repair and restore them.

EDB Recovery Software are well-designed and exclusive applications that allow you to extract all user mailboxes from a corrupted Exchange database and restore them safely.

Resolving 'Unable to create a new log file' Exchange Server Error

2009-12-14T02:14:00.000-08:00

Transaction log files contain the uncommitted data of an Exchange database. When an EDB (Exchange database) file crashes, the transaction log files act as disaster recovery means as they bring the database to a consistent state. For these reasons, it is recommended to store transaction logs on a different drive to avoid disk failure consequences that can affect the database. At times, Exchange Server observes issues when writing data to the drive where log files are stored. This can occur out of several reasons, such as file system issues, antivirus software problems, disk concerns etc. You need to troubleshoot the root cause. However, if the database is still inconsistent, you should restore the damaged database from backup or apply Exchange eseutil tool. Alternatively, you can opt for using an EDB Recovery Software to recover the damaged database.

For example, you might receive the below error with your Exchange Server:

“Unable to create a new log file because the database cannot write to the log drive. Drive may be out of space or incorrectly configured. Check file system, drive space, and antivirus settings.”

This error is logged with event 413 in application event log.

Cause

The possible reasons for the above error to occur depend on the error number described in the event description section, as follows:

1.Error -1022 = Jet_errDiskIO: This error occurs due to general disk I/O errors that resist the access of requested database page or checking a file.
2.Error -1032 = Jet_errFileAccessDenied: The error indicates that Exchange Server cannot access the file, probably because it is read-only or is in use by a process (virus checking or backup process).
3.Error -1811 = Jet_errFileNotFound: The error -1811 implies that Exchange cannot found the log file because it is missing or has mismatching signature with the database. It can also occur if the log files are stored on an unsupported network storage, failed drive or deleted by an antivirus software.

Solution

You need to apply these methods to solve the given issue:

1.Make sure that the log drive file system is free from errors by running chkdsk
2.Check for system related problems in system log
3.Check for the write permissions and available space on the disk
4.Make sure that an antivirus software is not running
5.Change the folders' permissions containing information store file to default

After running the above steps, make sure that the database is consistent. If not, you should restore it from backup. When there is no valid backup, you can run hard recovery for the database using eseutil
/p and isinteg -fix commands. But the command deletes the corrupted data instead of repairing it. Thus, you should make a backup first.

To repair the database safely, you should use an EDB Recovery utility. These are perfect Recover EDB Software equipped with database-aware algorithms to repair the corrupted Exchange database and extract the user mailboxes.

Stellar Phoenix Mailbox Exchange Recovery is a powerful tool that repairs corrupted Exchange database created with Exchange Server 5.5, 2000 and 2003. The comprehensive EDB Recovery Software product can restore all the user mailboxes as PST file, directly importable within MS Outlook. The tool is compatible with Windows 7, Vista, XP, 2003 and 2000.

Error configuring message service after Running Exmerge Tool

2009-12-10T20:26:00.000-08:00

Microsoft Exchange Mailbox Merge tool or Exmerge.exe allows you to extract mailboxes' data from an Exchange running computer and then merge it into same mailboxes stored on a different computer running Exchange Server. The tool copies the required data from the root server into .pst files and then merges it in the personal folders into mailboxes stored on the target server. At times, you cannot open the .pst files after using Exmerge.exe to extract the data to another Exchange Server database. This can occur due to incompatibility issues, new format of Outlook for PST, incorrect .pst file privileges or database corruption. As a result, the database becomes corrupt and you need an efficient Exchange Repair solution for Microsoft Exchange Server. For example, when you try to run Exmerge.exe to move data from an Exchange Server computer to another, you may receive the below error for various users: “Error configuring message service (MSPST MS) (MAPI_E_EXTENDED_ERROR) (CmapiSession::CreateEMSPSTProfile). Error opening message store (MSEMS). Verify that the Microsoft Exchange Information Store service is running and that you have the correct permissions to log on. (0×8004011d).” You cannot open the related .pst files. Cause The Exchange database is corrupted due to incomplete or improper merge operation. This can also occur due to insufficient .pst file permissions. The database corruption can also result because of unexpected shutdown and virus issues. Solution You should make sure that you use the latest version of Exmerge utility and the .pst files are not marked as read-only. For removing the read-only attribute from .pst file, you need to click its Properties and clear the associated check box. To restore the lost data for damaged database, you need to use your last backup. If this is absent or seems to be invalid, you need a third-party mailbox extraction tool. Termed as Exchange Repair software, these tools can repair and rebuild a corrupted Exchange database well while maintaining its integrity. The Exchange Server Repair solutions are highly competent to extract database mailboxes by using powerful scanning algorithms. Also, these tools are easy-to-use products with a graphically rich user interface. Stellar Phoenix Mailbox Exchange Recovery is an advanced and non-destructive utility that employs powerful scanning algorithms to repair a damaged Exchange Server database. It is compatible with Exchange Server 5.5, 2000 and 2003. It is a comprehensive MS Exchange Repair solution with impressive set of features and options. The tool extracts user mailboxes in individual .pst file format files.

Information Store Fails to Start with 4294966277 Error

2009-12-08T23:13:00.000-08:00

The space available in Exchange Information Store databases exists a list of pages. This space is called space tree, which is held as binary tree. An Exchange Server starts consuming high CPU percentage and showing slow performance factors if this space tree gets highly fragmented. Such problems can be resolved by running eseutil /d command, which shrinks the size of space tree and thus, provides offline defragmentation. On occasion, the process is left half-way through. If this event occurs, it could prevent Information Store from starting for the reason that database is corrupt. To restore the database, you are suggested to apply your last online or offline backup. If this too fails, you should use Exchange Server Recovery software to scan and repair it. To exemplify, you might come across an error message 4294966277 after you run offline defragmentation using eseutil /d command. The information store fails to start after you receive this error. When you view the application event log, it reveals error 0xfffffc05 while initializing the database. The event is marked with 1120 ID. Cause When you perform offline defragmentation of Exchange database, the database is first copied to a temporary file to perform the procedure. After it completes successfully, the defragmented database is them copied back to the original location to overwrite the original database. The above error occurs when the tool doesn't complete the copy back operation of temporary database to original location. This leaves the database in damaged state. Solution The temporary database file is not deleted until the copying operation completes. So, you can use it to manually copy the database, provided it is intact. 1. For a single database, you can execute eseutil /g d:\tempdfrg.edb command to check the consistency of the temporary database file. If it gives clean results, you can copy the database to D:\Exchsrvr\Mdbdata folder after renaming the original one. You should then rename the copied database to correct database. 2. If you defragmented both Priv.edb and Pub.edb databases and affected database is unknown, you should first check them for integrity using eseutil /g command. The database that fails the test should then be checked for size and compared with the size of temporary file. You can then copy the affected database by following steps, as above. If the temporary database fails the integrity check, it is damaged too. The database corrupted in this way should be restored from backup. However, when no backup is available, you need to opt for powerful third-party Exchange Recovery solutions. Exchange Server Recovery software are intelligent utilities to scan and repair damaged Exchange databases, while maintaining their integrity. Stellar Phoenix Mailbox Exchange Recovery is a feature-rich utility that employs powerful scanning algorithms to repair a damaged Exchange database. It supports Exchange Server 5.5, 2000 and 2003. It is a safe Exchange Recovery utility with impressive features. The tool extracts user mailboxes in individual .pst file format files.

Exchange Database Verification Failed because of no Page Data

2009-12-05T01:56:00.000-08:00

An Exchange Server database can get corrupt for several reasons, which include unexpected power failure, corrupted log files, network errors, virus infection and others. Consequently, the database may stop and fail to mount. You can try repairing the database using eseuitl utility. If this fails too, it compels you to apply the latest backup available or repair the database by an EDB Repair product. For instance, you might come across the below error when dealing with Microsoft Exchange Server: “Database page read failed verification because of no page data.” It further suggests to move the existing databases to a new hardware. The error is logged with event 476 in application event log. Cause The above error means that the database read operation has failed It generally occurs with error 1019. The causes are: 1.The specific database page that has been referenced within the database file is expected to be in use, but Exchange finds it empty or uninitialized. 2.A page may fail its checksum test with error -1018. But if the page number field that is in use is 0x00000000, the checksum failed page will show -1019 error instead. 3.File is corrupt and as a result, it maps some pages into database file that are not associated with it 4.Logical links or pointers between database pages are not correct The event 476 can also be related to -1018 error that indicates checksum mismatch and is caused generally due to hardware issues. Solution: You should check your system for related hardware issues if the database corruption problem is persistent. Replace the hardware and upgrade your firmware and/or disk controller if required. To repair the corrupted database, you can run eseutil /p command, which is a hard recovery option in Exchange database. Later, you need to execute eseutil /d and isinteg -fix commands. Exchange hard recovery performs page-level recovery and deletes the pages that it finds corrupted. So, it is recommended that you use safe EDB Repair Software. These third-party utilities let you perform easy and secure EDB Repair without any changes to database content, structure and metadata. Stellar Phoenix Mailbox Exchange Recovery is a reliable and advanced recovery tool for repairing corrupted Exchange databases. It repairs and restore individual mailboxes in .pst files. The comprehensive EDB Repair Software supports Exchange Server 5.5, 2000 and 2003. The tool restores all emails and other objects from corrupted database.

Exchange Database Corruption after Installing SP2

2009-12-02T04:06:00.000-08:00

Microsoft Exchange Server 2003 SP2 offers new features, more reliability and easier administration over its earlier counterparts. SP2 is a cumulative update that improves the Exchange messaging environment by including improvements in mobile messaging, mailbox and protection against spam. Before you upgrade your servers to Exchange Server SP2, it is recommended that you make complete backup of system state, file system and most importantly, Exchange databases. This assures of data availability in case the installation goes wrong in any way. But cases occur when your Exchange databases get corrupt when no clean backup is present. In such situations, you should use a powerful Exchange Server Repair product that can use safe scanning algorithms to repair a corrupted Exchange database. For instance, you can consider a scenario describes below: 1.You run Exchange Server 2003 SP1 or an earlier version 2.You decide to upgrade to Exchange Server 2003 SP2. During the installation of SP2, the setup failed to stop ExIFS (Exchange Installable File System) service but continues with no notice 3.After this, when you try to mount Information Store, it fails and events 470, 9519, 9518 and 104 are logged in the application log. Cause The above symtoms suggest that Exchange database may have got corrupted due to installation of SP2. It can also occur if an antivirus software is scanning the Exchange databases. Solution Before making any database restoration attempts, you should make sure that Exchange databases are excluded from any antivirus scanning. If databases appear as corrupted, you should consider these suggestions: 1.Try repairing the corrupted database by running eseutil /r command 2.If it fails, restore the database from the last backup you have 3.When no clean backup is available, you should use a Exchange Repair software. Exchange Server Repair products are highly competent utilities with powerful scanning algorithms to repair a corrupted Exchange database. These software are infallible solutions to any issue of database inconsistencies. Equipped with graphically rich interface and options, such software provide guide you through easy to implement procedure of repairing the database.

Microsoft Exchange Server: Emails Fails to be Delivered

2009-11-25T01:09:00.000-08:00

If Exchange Server fails to deliver any email message to the target recipient, it generates a Non-Delivery Report. The causes include expired or inactive accounts, SMTP issues, non-existent accounts, firewall interoperability concerns, email address misspelling and more. However, the most scaring one is when it generates NDRs because of corruption in Information Store databases. If Eseutil fails to repair the database in such cases, you might need to restore it from the backup or use a third-party Exchange Server Recovery software that could repair the database effectively. For an instance, consider that a user connected to Exchange Server sends an email message. The email fails to be delivered and the sender receives an NDR, similar to below: The following recipient(s) could not be reached: 'UserName' on Date and Time The e-mail system was unable to deliver the message, but did not report a specific reason. Check the address and try again. If it still fails, contact your system administrator. ServerName.Domain.com #5.0.0 Additionally, you might receive events 1706 or 327 recorded in Application log in Event Viewer after increasing the MSExchangeTransport diagnostic level in Exchange System Manager. Converting error 1017 and 1310 of error 327 through Error.exe results errors: “JET_errInvalidTableId” and “JET_errRecordDeleted” Cause The issue could occur due to the below possible reasons: 1.Exchnage Installable File System or /Exchsrvr folder and its subfolders have been scanned by an anti-virus software 2.Exchange Server information store databases are corrupted or damaged Such error cause difficulties while reading or writing data to the information store databases and hence the above errors result. Solution Follow these steps to resolve the issue: 1.Dismount the mailbox store while making sure that Exchange Server Information Store service is running 2.Try to defragment the database using eseutil /d utility 3.Check and correct information store databases integrity using Isinteg.exe utility 4.Mount the database and check if the problem persists 5.If it still continues, use a backup to restore the damaged databases 6.If no clean backup is available, use a Exchange Recovery Software to repair the database. Exchange Server Recovery software are powerful tools built with advanced and safe algorithms to repair a damaged Exchange database and extract the user mailboxes. Stellar Phoenix Mailbox Exchange Recovery is a high-end Exchange Recovery tool to safely extract all the mailboxes from damaged databases created with Exchange Server 5.5, 2000 and 2003. It is a non-destructive Exchange Server Recovery product that can restore all objects including emails, email properties, tasks, drafts and more.

What are the Limitations of Eseutil Utility in MS Exchange Server?

2009-11-17T23:30:00.000-08:00

Microsoft Exchange Server is a widely used and reliable method of creating a messaging collaborative environment. But in some cases, the Exchange Server Database (EDB) file may get damaged and you come across critical data loss situations. To handle the corruption situations, Exchange Server provides an inbuilt utility- Eseutil /p. It handles majority of EDB corruption situations and let you easily perform Exchange Server Recovery in quick way. The Eseutil /p is repair method for Microsoft Exchange Server. This procedure corrects most of the EDB corruption like issues and thus allows you to access your data. This utility works on ESE (Extensive Storage Engine) and the page level, not on the application level. Repair process goes through database and examines damaged pages and critical structures of database. After you perform application level repair, using Isinteg tool is required. Though, it is useful and effective tool, but the utility has a number of limitations that restrict its use in some situations. Some common situations are as underwritten: 1. The biggest disadvantage of this utility is that it removes the damaged pages that it can not repair. In this case, you may lose your critical emails, calendar entries, appointments, contacts and other data from the EDB file. 2. This tool needs clean shutdown of your system to process. In case of dirty system shutdown, it does not work and can not repair the damaged database. 3. Incorrect procedures performed while using this tool may lead to severe corruption and make all of your critical files difficult to repair. Limitations of this this tool shows that its applications would not carry out successful Exchange Recovery, if you try it in critical situations of corruption. If the database is not repaired completely, it could be disastrous to use it. In such situations, it is required to use any alternative method to repair damaged EDB file. The alternative method comes in the form of Exchange Server Recovery applications that repairs entire damaged file without altering original data from it. The tools use high-end scanning techniques to methodically scan entire EDB file and extract all of the damaged objects like emails, notes, contacts, tasks, attachments etc. from it. The Exchange Recovery software are built-with simple and interactive graphical user interface and thus do not alter original data of the Exchange Server database. Stellar Phoenix Mailbox Exchange Recovery is the best ever made Exchange Recovery Tool to repair damaged EDB files. It works well with Microsoft Exchange Server 5.5, 2000 and 2003. It repairs and restores all of the EDB file objects in most of the EDB corruption situations.

Error 0xfffff05b Post Applying Exchange Server 2000 SP3 or Later

2009-11-16T20:39:00.000-08:00

A compressed NTFS partition can cause several problems, if is made to store Information Store databases. Some of them are high CPU usage, delays when enumerating large NTFS directories and performance issues with many files. It can even corrupt the Information Store and prevent it from starting when it reaches to about 4 GB in size. Also, Exchange Server 2000 SP3 and Exchange Server 2003 do not support compressed Information Store. So, if you upgrade to any of these versions and store Information Store databases are stored on compressed NTFS partition, odds are that they might fail to mount. However, if the database are corrupted due to compression, you will need to restore them from backup or apply soft recovery commands. At times, when it doesn't work, you need a powerful Exchange Server Recovery solution to repair the corrupted databases. Consider you upgrade Exchange Server 2000 SP2 or earlier to Exchange Server 2000 SP3 or later. After you install the upgrade, when you try to mount the Information Store databases, the operation fails. When you view the application log of Event Viewer, it shows error 0xfffff05b with Event IDs 505 o r 9519. Cause As discussed, this issue occurs when you apply Exchange Server SP3 or any later version to a compressed NTFS partition containing Information Store databases. These versions automatically decompress database files, which are equal to or smaller than 128 MB in size, but prevent them from starting if are of greater size. Exchange Server database files require sector independence to achieve log-based recovery after any disaster. But if you compress these files, the condition is invalidated, which can corrupt them. Solution To solve the existing issue, following steps are recommended: 1.You should dismount all the Exchange databases. 2.You need to decompress the root folder of Exchange databases and log files. 3.You should defragment the databases and remount them. However, if the databases are corrupted because of NTFS compression, you need to restore them from backup or run Eseutil /r to perform soft recovery. Also, there are various Exchange Recovery products that can work for correcting database corruption. Exchange Server Recovery are high technology based tools that incorporate safe scanning algorithms to repair a damaged Exchange database. Stellar Phoenix Mailbox Exchange Recovery is a fully-featured and secure tool to perform systematic repair of damaged Exchange databases created with Exchange Server 5.5, 2000 and 2003. It is a comprehensive Exchange Recovery tool that extracts all user mailboxes by converting them into individual Outlook usable .pst files.

Top 10 Things About microsoft Exchange Server 2010

2009-11-12T02:01:00.000-08:00

Source: http://windowsitpro.com/article/articleid/103132/tony-redmonds-top-10-things-about-exchange-2010.html

At Microsoft Exchange Connections this week in Las Vegas, Exchange expert Tony Redmond delivered a keynote addressed entitled "Top 10 Things You Need to Know About Exchange 2010." With Microsoft's announcement earlier this week at TechEd Europe in Berlin about the immediate availability of Exchange Server 2010, Redmond's topic was well chosen, and the keynote was well-attended. For those who couldn't be there, here is Redmond's top 10 list.

1. Exchange 2010 is release 3.2 of Exchange Server—What Redmond means by this statement is that Exchange 2010 is the second version of the third generation of Exchange. The first generation includes the versions before Exchange 2000; the second generation is Exchange 2000 and Exchange 2003. The third stage began with Exchange 2007, which marked a fundamental change in the architecture of Exchange organizations. As the second release of this generation, Exchange 2010 should be past the initial growing pains that such drastic changes bring about.

2. First fundamental refresh of the Information Store since 1996—The improvements or upgrades to the Store include a larger database page size (up to 32kb from 8kb in Exchange 2007) and improved I/O, which is more sequential and less random. Because of these improvements, single instance storage (SIS) has been eliminated as no longer important. Also, storage groups are gone; management is intended to be by the database.

3. New software-based approach to high availability—High availability is built in to Exchange 2010 through Database Availability Groups (DAGs), which let you replicate databases to multiple servers with automatic failover in the event of problems. This architecture also introduces the concept of incremental deployment—that is, you can add servers and mailboxes as you need them; you don't have to plan everything before you even begin.

4. Hosted Exchange and on-premises are equal (almost)—Exchange 2010 was developed from the beginning to be scalable as a cloud-based solution as well as deployable in your on-premises data center, and it has received extensive testing through Microsoft's online initiatives. Therefore, it's clearly ready and able to be successfully deployed as a hosted service, although a few features might still be available only with on-premises deployments.

5. No upgrade path, must install on fresh hardware—I suspect this is a point that still might be unpopular with many users. Redmond explained that because you need to carefully consider your underlying OS, it makes sense to do fresh installs rather than upgrades. Exchange 2007 had the same situation; however, keeping in mind that this version is within the same generation, no doubt many admins expected the opportunity of in-place upgrade at least if they were already on Exchange 2007: no such luck.

6. More fully developed message compliance features—Compliance features in Exchange 2010 build on the good start of Exchange 2007 and provide a more feature-rich and customizable experience. Although the new personal archive isn't specifically a compliance feature, it can be used in conjunction with retention policies and rules to aid in better mailbox management. Improvements to the transport dumpster (what Redmond called Dumpster 2.0) let it keep track of all edits and deletions for better visibility of end user actions. And Exchange 2010 also introduces cross-mailbox search capability, which is a great first step toward e-discovery.

7. Role-Based Access Control (RBAC) replaces ACL-based permissions—With RBAC, users see in the GUI only functions they have permissions to perform; this restriction applies also to PowerShell-based management and the ability to use only cmdlets that are authorized for assigned roles. Redmond did mention the need to be careful assigning roles or you could end up locking yourself out of the management areas you need to be in, with no way back.

8. PowerShell 2.0—As you've no doubt seen, Exchange 2010 adds many new features, and that means many new Windows PowerShell cmdlets to manage things—hundreds, in fact. Additionally, PowerShell 2.0 adds remote management capability so you no longer need to work locally to get the job done. Redmond warned to be sure to test your PowerShell 1.0 scripts because some cmdlets have been removed and some might work differently in 2.0.

9. Exchange Control Panel (ECP)—You can still manage Exchange 2010 with Exchange Management Console (EMC) and Exchange Management Shell (EMS), but now you also have the option to use the browser-based ECP, giving you additional remote management capabilities. You can also use ECP to delegate some functions to end users, such as simple password resets—and thereby save lots of call to the Help desk.

10. And lots more—OK, Tony, I think you're cheating a little with this one, but in a well-meaning way. After all, there's a lot of worthy stuff to talk about with Exchange 2010.

Redmond's list of more items included such things as MailTips, Exchange Web Services as API, UM upgrades such as personal attendants, and of course the big improvements in Outlook Web App (formerly Outlook Web Access, but still OWA).

Resolving “The private store could not be update” Error in Exchange Server

2009-11-11T20:30:00.000-08:00

In Exchange Server 5.5 and all of the earlier versions of Microsoft Exchange Server, it is necessary to run Isinteg -patch command line utility after restoring the Exchange Server Database (EDB file) from offline backup. This is not required in Exchange Server 2003 and 2000. For this operation to be completed successfully, the EDB file must be set to enable overwriting by the restore procedure. But in some cases, the Isinteg -patch operation can not complete successfully and you come across some error message. In these circumstances, the EDB file becomes inaccessible and you come across data loss situations. In order to retrieve data and EDB file objects, Exchange Server Recovery is required. In a practical scenario, when you run the Isinteg -patch utility on Microsoft Exchange Server that is running on Microsoft Cluster Server, the process may fail halfway and you might come across the below given error message: “The private store could not be updated Reason: JET_errKeyDuplicate” In these cases, the restore operation can not be completed until the Isinteg -patch command runs successfully. Thus, the EDB file become inaccessible and results into critical data loss situations. At this point, you are required to go for Exchange Server Repair by resolving it. Cause This problem occurs on a database, which is forklifted from any standalone Exchange Server computer to the clustered MS Exchange Server computer. This behavior is known to take place if _CLUSTER_NETWORK_NAME_ environment variable contains a wrong value. This situation generally takes place due to typographical error. Resolution Before running Isinteg -patch command on Microsoft Exchange Server computer, which runs on Microsoft Cluster Server, then you must set environment variable _CLUSTER_NETWORK_NAME_ to Exchange Resource Group network name. When this method can not resolve the problem, Exchange Server database restoration from the offline backup remains incomplete and thus the database remain damaged. In these circumstances, it becomes essential to repair and restore damaged database and retrieve all of its objects using Exchange Server Repair applications. These are powerful third party applications, which employ high end scanning methods to thoroughly scan the damaged database and retrieve all of its objects. The Exchange Server Recovery software are completely easy to use as they come equipped with interactive and simple graphical user interface. With read only and non destructive conduct, these tools are completely safe to use. Stellar Phoenix Mailbox Exchange Recovery is most effective Exchange Recovery tool to handle all sorts of EDB corruption situations. It supports recovery from EDB files of Exchange Server 2003, 2000 and 5.5. This software is designed for Microsoft Windows 2003, XP and 2000.

Event 217 and 478 while Backing up Exchange Database

2009-11-09T04:32:00.000-08:00

Exchange Server storage groups and databases are the most vital component of recovery when the server crashes. You might observe typical symptoms with a corrupted Exchange database. For instance, you may fail to backup it. When it occurs, the corresponding event indicating the failure is logged in application event log, which helps you to deduce the cause. However, a corrupted Exchange database should be restored from backup. In case of unavailability of backup, you need an effective EDB Recovery product to repair and restore it. For example, you might encounter the below event logging into application log of Exchange Server after failing in attempts of backing up the Information Store: Event Type: Error Event Source:ESE Event Category:Logging/Recovery Event ID: 217 Date:10/25/2007 Time:12:15:31 PM User:N/A Computer:EXCHANGE Description: Information Store (5484) First Storage Group: Error (-613) during backup of a database (file D:\Program Files\Exchsrvr\mdbdata\priv1.stm). The database will be unable to restore. The error is usually accompanied with event 478. Cause Event 217 typically indicates backup failure and event 478 shows database corruption due to hardware issues. Event 217 might also be encountered due to Exchange beyond EOF (End Of File) condition. Solution Make sure you install all the latest updates and hotfixes available for your Exchange Server. To correct the corrupted database issues, you should perform steps, as follows: Use your last online backup to restore the Information Store databases Try to move mailboxes to another store if you are using Enterprise edition of Exchange Server 2000 or 2003 If none of the above solution is applicable, try to repair the database. To do so, you need to use eseutil /p repair command and then eseutil /d command to defragment the database. But the command deletes the pages that it finds as corrupted. For safe database repair, you should run EDB Recovery Software that use safe algorithms to restore damaged Exchange databases. EDB Recovery utilities are high-end applications with interactive design that provide complete database repair results. These software are highly reliable and require no prior technical skills to operate them. Stellar Phoenix Mailbox Exchange Recovery is a powerful tool that provides systematic Exchange database repair. It is a secure EDB Recovery Software that supports Exchange Server 5.5, 2000 and 2003. The tool can restore mailboxes in individual .pst files, which can be directly accessed in Outlook. The software is enriched with a realistic approach to repair corrupted EDB file in each instance.

Error 1216 Logs when One or More Database Files are Inconsistent

2009-11-06T03:02:00.000-08:00

Exchange Server database files are the most important recovery elements, required to be rebuilt after information store crash. If you can successfully restore them from the last backup and all required transaction log files are available, you should replay them to get the database to the state that existed before the crash occurred. In case of any issues, eseutil repair utility can help, but can cause data loss. For safe database repair, use of Exchange Server Recovery software is recommended. These tools can diagnose and repair all database contents using advanced procedures. For instance, you might observe that Exchange Server storage group stops unexpectedly. If this leaves few database files unavailable for the server, you encounter the below error marked in the Application event log: “Information Store (4312) Database recovery failed with error -1216 because it encountered references to a database, 'D:\exchsrvr\mdbdata\PRIV2.edb', which is no longer present. The database was not brought to a consistent state before it was removed (or possibly moved or renamed). The database engine will not permit recovery to complete for this instance until the missing database is re-instated. If the database is truly no longer available and no longer required, please contact PSS for further instructions regarding the steps required in order to allow recovery to proceed without this database.” The corresponding event is logged with Event ID '0'. Cause All or few database files of storage group are inconsistent. Solution You can check the database file consistency by running Eseutil /mh command. If you find any database inconsistent, you should apply these methods to recover: Restore from backup. You can determine the logs required by executing eseutil /mh database_name | find /i "log required command. Play the log files, if available Perform hard repair using eseutil /p command, followed by eseutil /d and isinteg -fix commands If the database contains no important information, you can simply delete it and create a new one Corrupted database files can be safely repaired using Exchange Recovery products. Exchange Server Recovery applications are powerful tools that employ high-end scanning algorithms to repair damaged Exchange databases and provide you interactive interface to work with. Stellar Phoenix Mailbox Exchange Recovery is a fully-features tool to safely extract all the mailboxes from damaged databases created with Exchange Server 5.5, 2000 and 2003. It is a non-destructive Exchange Server Recovery product that can restore all objects including emails, email properties, tasks, drafts and more.

How to Solve Error 1120 and 5000 Starting Information Store Service?

2009-11-05T04:26:00.000-08:00

The core repository of data for Exchange Server is its Information Store service, which is consisted of both public folder and mailbox store data. The store service basically implements the Exchange Server store. If Microsoft Exchange Information Store Service (MSExchangeIS) does not start, one of the top reasons is that its database(s) are corrupted. Among other reasons, this behavior primarily occurs as an after-effect of abnormal shutdown of Information Store. At this point, you should perform soft recovery or restore the database from a previous online backup. If this doesn't work, it is suggested to use EDB Repair tools instead of hard recovery as it can cause data loss. To exemplify such MSExchangeIS scenarios, consider you try to start the Information Store service in your Exchange Server, but fail to do so. When you view the Event Log with MSExchangeIS as the source, you find events 1120 and 5000 recorded as the failure entries. These errors show that the Exchange databases are in inconsistent state. Cause These errors occur when the following conditions are true: 1.You perform Eseutil.exe hard recovery operation for Priv.edb file to fix its inconsistency errors that occurred due to unexpected shutdown of Information Store. 2.The earlier transaction log files don't exit and are deleted 3.No hard recovery is performed for Pub.edb file As a result of the above sequence of steps, Priv.edb is consistent, but Pub.edb is still inconsistent due to the absence of transaction log files. Solution To solve the described issue, you can use any of the below methods: 1.Remove the Pub.edb file provided it contains no required data. Make sure you don't delete Edb.log file that is required by Priv.edb 2.Execute hard recovery for Pub.edb file using eseutil /p command 3.Use a third-party EDB Repair Tool to repair it EDB Repair software provide safe recovery for corrupted or damaged Exchange .edb files. These are feature-rich applications built with advanced technology for database repair. Moreover, you can use these tools without any prior technical skills as they provide an interactive user interface. Stellar Phoenix Mailbox Exchange Recovery is an advanced and safe EDB Repair Tool that employs powerful scanning algorithms to repair a damaged Exchange Server database. It is compatible with Exchange Server 5.5, 2000 and 2003. It is a safe EDB Repair utility with impressive set of features. The tool extracts user mailboxes in individual .pst file format files.

If this leaves few database files unavailable for the server, you encounter the below error marked in the Application event log: “Information Store (4312) Database recovery failed with error -1216 because it encountered references to a database, 'D:\exchsrvr\mdbdata\PRIV2.edb', which is no longer present. The database was not brought to a consistent state before it was removed (or possibly moved or renamed). The database engine will not permit recovery to complete for this instance until the missing database is re-instated. If the database is truly no longer available and no longer required, please contact PSS for further instructions regarding the steps required in order to allow recovery to proceed without this database.” The corresponding event is logged with Event ID '0'. Cause All or few database files of storage group are inconsistent. Solution You can check the database file consistency by running Eseutil /mh command. If you find any database inconsistent, you should apply these methods to recover: Restore from backup. You can determine the logs required by executing eseutil /mh database_name | find /i "log required command. Play the log files, if available Perform hard repair using eseutil /p command, followed by eseutil /d and isinteg -fix commands If the database contains no important information, you can simply delete it and create a new one Corrupted database files can be safely repaired using Exchange Recovery products. Exchange Server Recovery applications are powerful tools that employ high-end scanning algorithms to repair damaged Exchange databases and provide you interactive interface to work with.

Database Fails to Start when Circular Logging is Enabled

2009-11-02T20:51:00.000-08:00

Circular logging is a Exchange Server feature that implements recycling of logs. Microsoft Exchange Server writes the data to be committed to the database in transaction logs before actually writing it. If circular logging is enabled and four logs have been filled, it assumes that the first log as committed and thus, recycles the logs in order to save disk space. But it comes with a major flaw that prevents disaster recovery. If the database is corrupted while the feature is enabled, Exchange can only restore as far as the last backup is available. In case a suitable backup is unavailable, you are suggested to opt for Exchange Repair solutions that are powerful and safe too at repairing a corrupted Exchange database. For example, you observe an unexpected shutdown with an Exchange database. After this, when you try to start it, an 'JET_errFileNotFound' error is displayed with a numerical value, such as 4294965485, -1811 or 0xfffff8ed. When you view the application event log, it shows events 1120 and 5000. Cause Events 1120 and 5000 generally show database inconsistency that prevent the database to start. You should see their description for the exact reason. One probable cause could be that circular logging is enabled and error lies in checkpoint file, usually Edb.chk file. Since the circular logging is enabled, Exchange deletes the log files immediately after writing the data to the database, for which the information is traced out by Edb.chk file. Now, if a process blocks the Edb.chk file for a considerable period of time and prevents Exchange to update it, the file may get deleted before it could be updated. Thus, the checkpoint gets lost if the database suffers an unexpected stop. When you restart the server, the Edb.chk file points to a log file that doesn't exit anymore and hence, the database doesn't start. Solution If the exact cause is known and the errors are occurring only because of Edb.chk file, delete it and database service. But if the cause is different, the database might get damaged. To achieve recovery, you should not use eseutil /r command without /is or /ds switches. This is because at this point, a new Edb.log file can get created and Exchange may try to repair using incorrect set of log files. Though you can delete the Edb.chk file, but the database remains corrupted. For getting successful results from a corrupted Exchange database, it is suggested to use Exchange Recovery products in case if no good backup is there. Exchange Server Repair tools are high-end and safe database repair utilities that can repair and restore a corrupted Exchange database. Stellar Phoenix Mailbox Exchange Recovery is a fully-competent tool to perform systematic database repair of damaged Exchange files created with Exchange Server 5.5, 2000 and 2003.

E00.log is Missing and Database Doesn't Mount with Event 9518 and 455

2009-11-02T03:52:00.000-08:00

Transaction log files is the disaster recovery method used by Exchange Server to bring its databases to a consistent state post crash. The current transaction log data for a database is stored in E##.log file, which is further renamed to E#######.log when reaches to 5MB in size. The '##' is basically the storage group identifier. Thus, for first storage group, the file is E00.log. The file may go missing or get corrupt It generally occurs because of antivirus scanning and can render the databases unmountable as a consequence. At this point, you should remove all the transaction log files from the root folder and try to mount the database. If the problem continues, Exchange database corruption might be the reason. So, you need to use Exchange Recovery solutions to repair and restore the files. For instance, when you try to mount a mailbox or public store of Exchange Server 2000 or 2003, the operation might fail. When you view the application event log, you may come across events 9518 and 455. Cause E00.log file is missing or corrupt. This could occur if an anti-virus program is scanning or if anti-virus quarantine option is enabled for Exchange files. Microsoft suggests excluding Exchange databases, temporary files, logs, the IIS system files and the IFS drive from antivirus scanning on computer running Exchange Server. Also, it is recommended to avoid the scanning of folders that contain these files. By default, the folder containing temporary data is \Exchsrvr\MDBData. If your anti-virus software is scanning this folder, it might take the 'E00.log' as a virus or a file containing the virus. As a result, it will quarantine the 'E00.log' file and cause Exchange Server to crash. Solution 1. Stop all the Exchange services and exclude its files from antivirus scanning 2. Move all the log files from \Exchsrvr\MDBData to a temporary folder, except E00.chk, Res1.log and Res2.log 3. Start all the Exchange services and try to mount the databases 4. If you still cannot mount the databases, the problem lies is databases. They might be corrupt. Run eseutil /p to perform soft recovery, restore from backup or use a third-party Exchange Recovery product. Exchange Server Recovery utilities incorporate high-end scanning algorithms that can safely repair a damaged Exchange database and extract data from. Stellar Phoenix Mailbox Exchange Recovery is a powerful and safe Exchange Server Recovery utility to provide systematic repair for corrupted Exchange databases. It supports Exchange Server 5.5, 2000 and 2003. The tool can perform comprehensive Exchange Recovery for all database objects and extracts user mailboxes in individual PST files.

Checksum Errors on Exchange Server Database Pages

2009-10-30T05:24:00.000-07:00

A corrupted or damaged Exchange Server database exhibits abrupt behavior while normal database operations. However, you can deduce the root cause of the issue and sometimes, solution to the problem by application log entries. You should restore the corrupted database from the last backup, if is available and valid. In case of database issues, you are recommended to use EDB Recovery Software to repair the damaged database.

For example, consider you use Exchange Server 2003 or Exchange Server 2000. You use Exchange online backup to backup your Information Store database and fail to do so. When you view the application log in Event Viewer, you encounter the below error message:

“Information Store (2240) The database page read from the file "E:\program files\exchsrvr\mdbdata\priv1.edb" at offset 204275712 (0x000000000c2d0000) for 4096 (0x00001000) bytes failed verification due to a page checksum mismatch. The expected checksum was 303571876 (0x121823a4) and the actual checksum was 303571940 (0x121823e4). The read operation will fail with error -1018 (0xfffffc06). If this condition persists then please restore the database from a previous backup.”

This error is logged with event ID 474.

Cause

Error 1018 indicates JET_errReadVerifyFailure error.

It results because of checksum errors on database pages. The prominent reason for this error to occur is Exchange database corruption due to file system errors. If the disk subsystem is suffering from issues, like defective disk drivers, faulty controller or outdated or incompatible firmware, this could result into Exchange database corruption.

Solution

You can solve these problems by these methods:
1.Try to perform backup using different storage group located on a different server disk.
2.Diagnose and troubleshoot your Exchange Server running system for possible hardware issues
3.Update your system with the latest firmware and drivers updates available
4.If a clean data backup is available, restore your database
5.Perform hard repair of the database using Eseutil /p in case no suitable backup is present
6.Eseutil /p is a destructive repair operation that could delete the corrupted database pages.

To prevent the consequences, you should use safe EDB Recovery utilities. EDB Recovery Software are powerful tools to examine, repair and restore damaged Exchange databases using efficient scanning algorithms. These tools provide you graphically rich user interface and advanced features that result complete database repair.
