TITLE   :XWEB: OWA Cannot Send to SMTP User By Using X.400 Address
PRODUCT :Microsoft Exchange
PROD/VER:WINDOWS:5.5
OPER/SYS:
KEYWORDS:kbExchange550preSP4fix kbExchange550sp4Fix

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

 - Microsoft Outlook Web Access, version 5.5 Service Packs 1, 2, 3 
 - Microsoft Exchange Server, version 5.5 
-------------------------------------------------------------------------------


SYMPTOMS
========

If you use a browser such as Microsoft Internet Explorer to access Microsoft
Outlook Web Access (OWA) and you address a message to a Simple Mail Transfer
Protocol (SMTP) user who can only be reached over an X.400 Connector, the
address may be recognized incorrectly. When you send the message you receive an
immediate non-delivery report (NDR).

For example, if you address a message as follows

   To: [X400: c=fr; a=atlas; dda:rfc-822=<user_name>@hotmail.com]

when you click Check Names, the following information is displayed

   X400: c=fr; a=atlas; dda:rfc-822= [SMTP: <user_name>@hotmail.com]

and when you send the message you receive an immediate NDR.

CAUSE
=====

This issue can occur because the address parser treats a colon (:) as a
delimiter between address type and address, so only one colon is allowed in an
address. If an X.400 address for an SMTP user contains more than one colon, the
address is recognized as a pure SMTP address and the preceding terms are taken
to be the display name.

RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Exchange Server 5.5.
