TITLE   :XFOR: Messages from cc:Mail to Exchange Missing Address Info.
PRODUCT :Microsoft Exchange
PROD/VER:winnt:5.0,5.5
OPER/SYS:
KEYWORDS:exc5 exc55

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

 - Microsoft Exchange Server, versions 5.0, 5.5 
-------------------------------------------------------------------------------

SYMPTOMS
========

When Microsoft Exchange Server is used as a backbone between two Lotus cc:Mail
post offices, all of the messages that are sent from cc:Mail users that are
addressed to cc:Mail users on a different post office are rejected by the
Microsoft Exchange Connector for Lotus cc:Mail. A non-delivery report (NDR) that
is similar to the following is sent to the originator of the message:

   From: ~BEL01 at CCMAIL
   Sent: Wednesday, December 22, 1999 11:31 AM
   To: User, Test
   Subject: Undeliverable: test from bel02

   Your message was not delivered to all recipients.

   Subject: test from bel02
   Sent: 12/22/99 9:02:00 AM

   The following email address(es) were unknown:

   at PO_NAME

CAUSE
=====

This problem may occur if the Connector for cc:Mail cannot process the message
because the recipient address is incomplete in the TO field. To determine if the
recipient address is incomplete, use one of the following methods:

 - In the text of the NDR, look for a description that is similar to the
   following:

   The following email address(es) were unknown: at PO_NAME

   If the description is missing the user name portion of the e-mail address, the
   recipient address is incomplete. If the recipient address is complete, the
   e-mail address is formatted as "USER_NAME at PO_NAME."

 - If cc:Mail message archiving is enabled, a copy of the original message from
   cc:Mail is saved in the Exchsrvr\Ccmcdata\Export.bak folder. Open the CCM
   file and examine the message header. If the TO field is missing the user name
   portion of the e-mail address, the recipient address is incomplete.

This problem is caused by the cc:Mail version 8.3 Export.exe file.
