• 
  Server failure or Crash
  
• 
  File Header Corruption
  
• 
  Log Files Deleted
  
• 
  Dirty Shutdown due to power spate

The corruption of exchange database is so devastating that recovery becomes tedious. In order to overcome from such situation Microsoft has gifted the technical filed with some free utilities such as Eseutil.exe, Exmerge.exe, and Export-Mailbox. All these utilities tools convert the EDB to PST file and extract the mailbox in .PST file format. During severe corruption these tools also fail.

MS Exchange servers database face several errors. These errors create loads of trouble and the work also gets hampered. This leads to a trouble in opening of a database files.

For handling the above errors, verification of the permission of the EXCHSRVR folder should be done. System must be assured that it must have all the sub-folders and EXCHSRVR containing Exchange data.

If the database cannot be mounted, the trouble shooting of Windows NT file-level anti virus software must be done which is running on the Exchange Server. The log for the drive of input/output error must be checked. The path for the check file must be verified and corrected. The root cause must also be corrected and an updated back up must be retrieved.
