TITLE   :XCON: Domain Defined Attributes Value Is Not Displayed in NDR
PRODUCT :Microsoft Exchange
PROD/VER:winnt:5.5
OPER/SYS:
KEYWORDS:exc55 kbExchange550preSP4fix kbExchange550sp4Fix

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

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


SYMPTOMS
========

When you send an X.400 message to a distribution list and the message cannot be
delivered to one of the recipients, the non-delivery report (NDR) that you
receive may not contain the Domain Defined Attributes (DDA) value from the
recipient's address. As a result, you cannot determine which recipient did not
receive the message.

CAUSE
=====

When you send an X.400 message through an Exchange Server computer, the message
transfer agent (MTA) moves each recipient's distinguished name (DN) from the DDA
value to the X.500 portion of the originator/recipient (O/R) address. The MTA
moves the DN back to the DDA value before sending the recipient information to
the information store, but when the recipient report is generated, this DN is
not removed from the DDA value. When the recipient report is sent to the
information store using the X.400 Application Programming Interface (XAPI), the
DN is removed because it is not an Exchange DN. Because the DDA value no longer
exists, it cannot be displayed in the NDR.

RESOLUTION
==========

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