Like all other databases, Microsoft Exchange Server database also comprises of several tables. These tables consist of one of more trees and hold records and columns, which are identified as MAPI properties. At times, typically when the database is corrupt, Exchange Server cannot identify these tables as valid database tables. As a result, when attempt is made to access the database, application event log records an associated entry indicating the cause. However, to solve these problems, the prime solution considered for Exchange Recovery is to restore the database from backup.

Here, the mentioned problem has been narrowed down with the below error message. You can see this or similar error message logging in application event log with an associated event ID 448:

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

You can encounter this error message when trying to start Exchange Server, which occurs because mailbox store(s) cannot be mounted. Microsoft Exchange Server detects inconsistency in one of the Jet database table.

Note: Exchange Server database can get corrupt because of antivirus scanning, corrupted restore operation, damaged hard disk subsystem, and the like reasons.

User Action

1. Check the system log for determining possible hardware, file system, or driver related problems. If you find any such errors, take the corrective measure like, replace the hardware, repair the file systems, and update drivers.

2. Check whether or not database can mount. If it can, you can export its data to .pst files using ExMerge utility and then delete the corrupted database. If it cannot, you should restore it from last online backup, run eseutil /p repair utility followed by eseutil /d and isinteg utilties, or use a third-party Exchange Recovery Tool.

Microsoft Exchange Recovery software are more effective plus safer programs over Exchange eseutil repair utility. While eseutil /p command can delete the database pages, these software repair the database and extract its content without affecting the original database, and maintaining the same formatting and view.
