| Component: | Microsoft Exchange Message Transfer Agent |
| Message: | A fatal MTA database server error was encountered. The object reservation count for object <object name> has been decremented below zero. [<value> <value> <value> <value>] (16) |
| Explanation | |
|
The message transfer agent (MTA) encountered an internal processing error while processing a message or report object. This indicates a logic error or database integrity failure. The Microsoft Exchange Server disk may be full or a disk error may have occurred. The message transfer agent (MTA) service will stop if the disk is full. The MTA DAT files may be corrupt. |

| User Action | |
|
If the Microsoft Exchange Server disk is full, delete any unnecessary files. If you suspect a disk error, run Chkdsk. Verify that the \Exchsrvr\Mtadata directory exists. Stop and restart the 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. Contact Microsoft Product Support Services for assistance. |
