Message: A fatal internal MTA error occurred. Contact Microsoft Technical Support. An illegal GET from element name occurred at offset value. [valuevaluevaluevalue] (16)
   
Explanation
The message transfer agent (MTA) may experience a performance problem when expanding extremely large distribution lists. The problem can also be triggered if the recipient name field being transferred into the MTA is larger than the buffer space available.

If a failure occurred during the processing of a message, key routing information for some addresses on the recipients list may not be consistent upon restart, causing the error described above.

   
User Action
