The information in this article applies to:

  • Microsoft Exchange Server 4.0
  • Microsoft Exchange Server 5.0

This article was previously published under Q175964

SYMPTOMS

The Microsoft Exchange Server Message Transfer Agent (MTA) might stop processing messages and report an access violation when it receives a message from a foreign X.400 MTA. The Microsoft Exchange Server will generate a Windows NT Event Viewer Event ID 210 with a conversion error of 4097. The MTA will generate a Non-Delivery Report (NDR) and return a messages with the error:

Content-type unsupported.

CAUSE

This is caused by invalid encoding of a message by the foreign X.400 system. One specific cause is the message lists an improper length of the IPN ID. This can be detected by generating text event logging with logging level set to maximum for the APDU and X400 Services. Parsing the message at fault and reviewing the IPN ID will show that the length for the IPN ID field is invalid.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server, version 4.0. This problem has been corrected in the latest U.S. Service Pack for Microsoft Exchange Server version 4.0.
