XCON: Internet Message w/Message as Attachment Generates NDR

 Last reviewed: February 12, 1998
Article ID: Q177979
The information in this article applies to:
  • Microsoft Exchange Server, version 5.0

SYMPTOMS

Messages sent from the Internet to the Microsoft Mail Connector (MSMI) that contain embedded messages may be rejected by the MSMI with a Non-Delivery Report (NDR).

For example, when a message is sent from Microsoft Mail for PC Networks to an unknown address on the Internet via a Microsoft Exchange Server, you will normally receive an NDR for this message. The NDR may contain the original message as embedded attachment and has to pass through the Microsoft Mail Connector. At this point, the following Event Id is generated by the MSMI: 

   10000 MSExchangeMSMI
   MDBEF parsing failed on Attachment Information.

CAUSE

The embedded message is not handled correctly by the Microsoft Mail Connector Interchange service.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server, Version 5.0.

This problem has been corrected in the latest U.S. Service Pack for Microsoft Exchange Server version 5.0. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
