SYMPTOMS
When users send outgoing messages through an X.400 connector, those messages may remain in the outgoing X.400 protocol queue. The messages are not delivered. If you remove the first message from the queue, messages may be delivered successfully but may then again become stuck in the outgoing queue.



CAUSE
This problem occurs when a user who sends a message has an X.400 proxy address that contains a given name, but that does not contain a surname. An X.400 proxy address that contains a given name, but that does not contain a surname, is unsupported by Microsoft Exchange 2000 Server because this is not a valid X.400 address. Because this is an invalid X.400 address, Exchange 2000 Server should return the message to the sender as undeliverable, but it does not.

After you install this update, Exchange 2000 Server generates a non-delivery report (NDR) when it receives a message from a recipient who has an invalid X.400 proxy address (as described in the &quot;Cause&quot; section of this article). You must correct the X.400 proxy address for each user who has an invalid address.



WORKAROUND
To work around this problem, manually remove the message that is stuck from the X.400 remote delivery queue, and then make sure that the there is a valid surname in the user's X.400 proxy address.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
