User Action
Stop and restart the message transfer agent (MTA) service. If the error persists, run the Mtacheck.exe utility. Stop the MTA service, open a command prompt, and type Mtacheck/v /f c:\mta.txt. If Mtacheck removes objects from a database queue, it places each damaged object in a Db*.dat file in \Exchsrvr\Mtadata\Mtacheck.out. Check your drives and verify that core *.dat files are in the \Exchsrvr\Mtadata directories. The \Exchsrvr\Mtadata directory with *.dat files may be on more than one drive. Contact Microsoft Product Support Services for assistance.
