XWEB: Outlook Web Access Unable to Send Message to SMTP User By Using X.400 Address (257678)

The information in this article applies to:

Microsoft Outlook Web Access 5.5 SP 3
Microsoft Outlook Web Access 5.5 SP 1
Microsoft Outlook Web Access 5.5 SP 2
Microsoft Exchange Server 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. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
