Recently, one of our Exchange server is recording MSExchangeSA errors in the Event logs.

Event Type: Error
Event Source: MSExchangeSA
Event Category: General
Event ID: 5007
Date: 19/03/2010
Time: 10:09:23
User: N/A
Computer: COMPUTER
Description:

Event ID 5007: An error occurred during the message tracking decode operation. Function:ScOpen . <<0xc0070842 – The Server service is not started.>>

Event ID 5007: An error occurred during the message tracking decode operation. error from file: f:\tisp2\admin\src\libs\rpc\rwlog.cxx line: 517. <<0xc0070842 – The Server service is not started.>>

Event ID 1026: Unable to get information about the message tracking share ‘COMPUTER.LOG’. Error 0xc0070842.

Event ID 5005: The frequency specified for clearing the message tracking log file is not valid. The default value 10 will be used.

Our solution was that we noticed some of the server’s Automatically start services weren’t started. Once we restarted those services, these errors went away.
