How to deal with EDB File Error

Both Eseutil and Isinteg tools are stored in the Bin folder of the Exchange Server system. However, initially you require doing the following steps to run Eseutil.exe from command prompt

  • Click on Start>Run
  • In the run box, type “cmd” and press “ok”
  • Go to C:\Program Files\Exchsrvr\bin directory
  • Type Eseutil.exe in command line

Now to start recovering corrupt EDB database, use following Eseutil commands

Eseutil/P Primary name.EDB

If EDB files are severely damaged, then you should use Eseutil/p command. The command line to repair severely damaged private or public EDB file is:

Eseutil /p C:\Program files\Exchsvr\mdbdata\ primary name.EDB

primary name.EDB

After you have successfully repaired the EDB database with Eseutil /P command, run Eseutil /d command to defragment the repaired EDB file. Eseutil/d, usually helps in trimming the size of a repaired EDB folder by removing invalid and blank database pages.

Now once you have used Eseutil commands, you would require running Isinteg command on the Exchange Server. The command line will appear like this

Isinteg-s (Server name) –fix- test all tests
