TITLE   :XCON: Invalid Originator Address When Sending to X.400
PRODUCT :Microsoft Exchange
PROD/VER:4.0
OPER/SYS:
KEYWORDS:kbusage

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Exchange Server, version 4.0 
-------------------------------------------------------------------------------


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
