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.
