| Description | Verify that the Microsoft Exchange MTA service has started. Consecutive ma-open calls are failing with error <error code>. |
| Event Information | Explanation: The message transfer agent (MTA) is failing. The MTA might not be running. User Action: Ensure the service and its dependent services are running. If the service is not running, start the service. If the service does not start, search this message reference for MTA failures. Use the Mtacheck utility in the Exchsrvr\Bin directory when MTA errors are encountered. According to the information from some newsgroup post: This error may occurred when root hard disk free space is too low, where the Exchange server is installed. This problem can be resolved by freeing up some space on the hard drive. |
