The Message Transfer Agent check utility (Mtacheck) is designed to provide a soft recovery of a corrupted MTA database. It is automatically installed when Microsoft Exchange Server is installed and can be found in the %Exchange_Root%\Bin directory. This utility should be used when the MTA service will not start due to corruption or suspected corruption in the MTA database.
