Messages that are sent through an X.400 connector may remain in the outgoing X.400 queue (821177)


The information in this article applies to:

  • Microsoft Exchange 2000 Server

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.
