XADM: 1993 Private Extension Support on Per-Message Envelope

ID: Q145794


The information in this article applies to:
  • Microsoft Exchange Server, version 4.0


SYMPTOMS

When you send a message from a DEC All-in-One mail system to a Microsoft Exchange Server with the X.400 Connector, the message may not get to the intended Microsoft Exchange Recipient and the original sender may not receive a Non-Delivery Report (NDR). No errors will be recorded in the Windows NT Event Log.

However, messages sent from Microsoft Exchange to DEC All-In-One recipients flow fine. Additionally, messages sent from Microsoft Exchange to DEC with a read receipt requested will successfully return the read notification back to the Microsoft Exchange sender.


MORE INFORMATION

The 1993 X.400 recommendation supports a per-message envelope Private Extension. Digital Equipment's latest version of Mailbus400 MTA (v2.0) implements this extension. Microsoft Exchange Server version 4.0 does not support per-message envelope Private Extensions. Service Pack 2 (SP2) and Microsoft Exchange Server version 4.0a add support for per-message envelope and report content Private Extensions.

NOTE: Microsoft Exchange Server does not support per-recipient Private Extensions.


STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 4.0. This problem was corrected in Microsoft Exchange Server 4.0 U.S. Service Pack 2. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
