SYMPTOMS
When you send a message from Microsoft Mail through Microsoft Exchange Server 4.0 to an address on an X.400 messaging system, a reply to this message may not be possible. This occurs if you (the Microsoft Mail user) are not a Custom Recipient on the Microsoft Exchange Server, which can happen if, for example, directory synchronization is not yet finished.
CAUSE
The message will arrive at the remote X.400 system with an invalid X.400 originator address in the message header fields. The X.400 address will only contain a DDA Type and a DDA Value, which contains the Microsoft Mail Address. For example:
DDA Type=MS;DDA Value=Net/PO/User
This address is invalid because mandatory parts are missing. A valid address looks like this:
C=Country;A=Admin;P=Private;O=Org;DDA Type=MS;DDA Value=Net/PO/User
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. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
