TITLE   :XCON: MTA Deferred Delivery Message Generates NDR
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
========

The following Non-Delivery Report (NDR) may be received when sending messages
with a deferred delivery time after the message timeout:

   From: System Administrator
   To: 'x400 to user1'
   Sent: Monday, November 23, 1998 5:00 PM
   Subject: Undeliverable: test 2 on Friday
   Your message did not reach some or all of the intended recipients.

   Subject: test 2 on Friday
   Sent: 11/13/98 9:21 AM

   The following recipient(s) could not be reached:

   'x400 to user1' on 11/23/98 5:00 PM
   The maximum time for delivering the message expired
   MSEXCH:MSExchangeMTA:Site:Server

The NDR is received on the deferred delivery date, not immediately upon sending.

CAUSE
=====

The Message Transfer Agent (MTA) returns the message if the deferred delivery
date is after the message timeout. The default message timeout period is seven
days. When the deferred delivery date arrives, the MTA checks the message
timeout value, and displays the NDR for this message based on that date, instead
of delivering the message.

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:

   Q191014 XGEN: How to Obtain the latest Exchange Server 5.5 Service Pack

Please note that this fix must be applied to all Microsoft Exchange Server
computers in the message path, as each MTA on each server evaluates the deferred
delivery time and message time-out.
