SUMMARY
You can still set Diagnostic Logging on the MSExchangeMTA and check Message Transfer Agent (MTA) queues even when no MTA object is exposed in the Microsoft Exchange Server Administrator program.

The MTA will not be exposed if the version of Microsoft Exchange Server is not the Enterprise Edition and neither the Connectors disk nor the X.400 Connector disk has been installed.



MORE INFORMATION
If you are trying to troubleshoot a Microsoft Mail Connector or Internet Mail Connector (IMC) issue and no Message Transfer Agent object exists, you can still set logging levels and view queue information as follows:

Even when this is not available, logging can be set on the Diagnostic Logging property page of the  container. There are two ways to set Diagnostic Logging:  On the Diagnostic Logging property page, select MSExchangeMTA in the Services pane.

 MSExchangeMTA Diagnostic Logging can also be set by modifying the values in the following registry key:

 Start Registry Editor (Regedt32.exe).  Under the HKEY_LOCAL_MACHINE subtree, go to the following subkey:

   SYSTEM\CurrentControlSet\Services\MSExchangeMTA\Diagnostics  Modify the value. A value of 0 corresponds with None, 1 with Minimum, 3 with Medium and 5 with Maximum. Quit Registry Editor.</li></ol> </li></ul>
