Private Information Store (priv.edb) in MS-Exchange Server gets corrupt because of many reasons. These reasons include sudden server shutdown, malicious virus, anti-virus scanning, log file corruption, and human errors. Once the priv.edb file gets corrupt, you start getting nasty error messages on your screen. Due to these errors, data of the Information store becomes totally inaccessible. In such critical situations backup can be used. In case you don’t have a backup file, you have another option of using third party Exchange recovery software.
Consider a scenario, suppose you decided to defrag the Information Store. You do the same, to mount the database. But during this process, you receive an error message ''an invalid checksum''. When an eseutil /k priv1.edb utility is executed, below output gets received like this:
“ERROR: page 1004909 checksum failed ( 0x2f906db8 / 0xb0259cd4 )

Why this Error?
Above error message occurs due to corruption of Exchange Server or Private information store (Priv.edb) file.
How to Solve the Problem?
In order to resolving the above error message, you have to follow the below mentioned measures:
- Run ESEUTIL/D utility so that Exchange Server database gets easily defragmented. With the help of this utility, minor corruption problems of database could be easily solved.
- If still same problem persists, then it is better to restore the database from a valid backup.
- If backup is unavailable, then you can use third party Exchange Recovery software to repair the corrupt database.
These tools are specially developed for Exchange Server recovery. After performing recovery by these tools, corrupt Exchange Server database becomes free from logical corruption.
Stellar Phoenix Mailbox Exchange Server Recovery can be relied to achieve the successful Exchange recovery results. The tool restores mailbox items, such as contacts, attachments, appointments, journal, tasks, events, and e-mail messages in .pst file format. The tool is designed for MS Exchange 5.5, 2000, 2003, 2007, and 2010. It is also compatibility with Windows Vista, 7, XP, Server 2003, and 2000.
