TITLE   :XCON: NDR When Replying All to Message Sent to Moved User
PRODUCT :Microsoft Exchange
PROD/VER:WinNT:5.5
OPER/SYS:
KEYWORDS:exc55sp2fix

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

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


SYMPTOMS
========

The Microsoft Exchange Message Transfer Agent (MTA) may return a non- delivery
report (NDR) similar to the following when a user attempts to Reply All to a
message:

   Your message did not reach some or all of the intended recipients.

   Subject: Test Message
   Sent: 10/30/98 11:00 AM

   The following recipient(s) could not be reached:

      "User in PAB" on 10/30/98 11:01 AM
         The recipient name is not recognized
         MSEXCH:MSExchangeMTA:SITE:SERVER

This problem may occur when the recipient's address was chosen from an old
personal address book (PAB) entry that had been originally selected as a custom
recipient in Container A, but had since been relocated to Container B.

CAUSE
=====

These NDRs occur because the PAB entry is storing an old distinguished name that
is no longer accurate for that custom recipient since the custom recipient has
been relocated to a new container. However, it should be possible to add an X500
distinguished name with the old address to the relocated custom recipient. The
MTA will be able to send the message, but if the recipient attempts to "Reply
All", they will receive an NDR when it attempts to send a message to the
incorrect distinguished name for the original recipient.

RESOLUTION
==========

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