TITLE   :XCON: Message Arrives with Blank To and From Fields
PRODUCT :Microsoft Exchange
PROD/VER:winnt:5.5
OPER/SYS:
KEYWORDS:exc55 EXC55SP3Fix

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

 - Microsoft Exchange Server, version 5.5 
-------------------------------------------------------------------------------


SYMPTOMS
========

An Exchange Server user receives a message in his or her Inbox, but the From and
To fields are blank.

CAUSE
=====

This behavior occurs in the following very specific scenario:

1. An Outlook user on Exchange Server sends a message with an attachment to an
   X.400 custom recipient through an X.400 Connector on which the "Remote
   clients support Mapi" option is selected.

2. The message arrives on a MARBEN X400 MTA and is read by a Microsoft Mail user
   connected directly to the MARBEN server through a MAPI transport developed by
   MARBEN.

3. The MS Mail user reads the message then forwards it to an Outlook user on
   Exchange Server.

4. The message is delivered in the correct mailbox, but when the Outlook user
   opens the message, the From and To fields are blank.


RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Exchange Server
version 5.5. For additional information, please see the following article in the
Microsoft Knowledge Base:
