If you are receiving the below error:

‘Microsoft Exchange Writer State Failed’ when running ‘vssadmin List Writers’ on your mail server within a command prompt.

or if your symantec backup exec is failing with the error below:

‘The VSS writer failed, but the operation can be retired. Failed during prepare snapshot operation when backing up your exchange mail stores.’

Restart the mail server or restart the information store, this should clear the issue.

Type VSSADMIN LIST WRITERS on your mail server and you should find the error has disappeared and your backup should run as normal.

If System writer is not listed when you check for the writers, run the below commands with elevated command prompt or you can create another bat file and run:
 
Takeown /f %windir%\winsxs\temp\PendingRenames /a
icacls %windir%\winsxs\temp\PendingRenames /grant “NT AUTHORITY\SYSTEM:(RX)”
icacls %windir%\winsxs\temp\PendingRenames /grant “NT Service\trustedinstaller:(F)”
icacls %windir%\winsxs\temp\PendingRenames /grant BUILTIN\Users:(RX)
Takeown /f %windir%\winsxs\filemaps\* /a
icacls %windir%\winsxs\filemaps\*.* /grant “NT AUTHORITY\SYSTEM:(RX)”
icacls %windir%\winsxs\filemaps\*.* /grant “NT Service\trustedinstaller:(F)”
icacls %windir%\winsxs\filemaps\*.* /grant BUILTIN\Users:(RX)
 
net stop cryptsvc
net start cryptsvc

Please ensure you have a recent backup of your server before going ahead with such changes. Always good to be on the safe side.
