PRODUCT :Microsoft Exchange
PROD/VER:winnt:4.0,5.0,5.5
OPER/SYS:
KEYWORDS:exc4 exc5 exc55 EXC55SP3Fix

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

 - Microsoft Exchange Server, versions 4.0, 5.0, 5.5 
-------------------------------------------------------------------------------


SYMPTOMS
========

The Microsoft Exchange Message Transfer Agent (MTA) mishandles deferred delivery
messages after the daylight savings time adjustments occur. The MTA will attempt
to deliver deferred messages either an hour earlier or later than expected until
all of the MTAs in the organization have been cycled. This problem is more
prevalent with messages that have been deferred in Outlook using the Options
button deferral method. Messages deferred through the Properties option on the
File menu do not experience this problem.

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:
