EDB Corruption When Defragmentation Fails

   Marvin Simmons     Updated On - 24 Jan 2019

Microsoft Exchange Server runs a defragmentation process to eradicate the unused Storage space and rearrange Mailbox store and Public folders and stored data, so that it can become manageable. Eseutil utility is used for defragmentation of Exchange Server database. It scrutinizes the basic structure of the database and rearranges it to enhance the performance of the database.

At times when you defragment the database, chances are that the process might fail half-way through. When the process gets stopped, user gets a temporary file Priv1.edb. When user renames this file, it gets disappeared. In similar situations, mailbox might have possibly corrupted and user cannot mount it. At this time, when you utilize Eseutil/MS (to dump the space usage), the operation is terminated by the error message mentioned below:

Error -2211 (JET_errSLVHeaderCorrupted, SLV file header contains invalid information)

After getting this error message, when a user uses Eseutil /P to repair the database, user comes across the following error message saying:

Checking database integrity. Operation terminated with error -1206 (JET_errDatabaseCorrupted, Non database file or corrupted db) after 1.912 seconds.

These actions leave you in a situation where you are unable to access Exchange Server database and cannot retrieve even a single bit of data from the database. Users, dealing with this situation, come across these error messages due to damaged Exchange Server database. The database corruption might be a consequence of dirty system shutdown, virus invasion, over-sized EDB file etc.

Actually, the reason behind data loss doesn’t matter here, what matters is how can users retrieve their precious data. The solution to this problem is Exchange Server recovery; Exchange recovery is a process in which the damaged database is repaired by utilizing advanced EDB repair software thereby restoring precious database. EDB repair software is easy to use utility that enables user in all cases of EDB corruption and can recover all of EDB objects.

Kernel for Exchange Server is an advanced exchange repair and exchange recovery software and supports recovery from EDB files created with Exchange Server 5.0, 5.5, 2000 and 2003. Moreover, with its three advanced recovery modes, the tool scans and scrutinizes the entire database and gives you productive results of Exchange Server recovery.

The free evaluation version of the software provides an overview of the software before purchasing the Full version. The demo version with demo limitations will repair and recover the Exchange Server items but will not save them.
