SYMPTOMS
========

When you send a message using a Microsoft Outlook client and use the option for
delayed delivery by selecting the Do Not Deliver Before option, the message may
be sent at the wrong time by the Microsoft Exchange Server computer.

CAUSE
=====

The Microsoft Exchange message transfer agent (MTA) service does not recognize
the change from Standard Time to Daylight Savings Time, and vice versa. In this
case, the sending delay (or ahead of time difference) would be one hour. Any
other time periods are not related to this article.

WORKAROUND
==========

There are two options to workaround this problem:

- Restart the MTA service on the Microsoft Exchange Server computer.

  -OR-

- To temporarily workaround the problem (per message) without restarting the
  MTA service, set the delayed delivery options using the Send Options For This
  Message dialog box by performing the following steps:

  1. From the message window, select Properties from the File menu.

  2. Click Send Options.

  3. Click the Microsoft Exchange Server tab.

  4. Under Send This Item, select the appropriate number of minutes, hours,
     days, or weeks.

STATUS
======

Microsoft has confirmed this to be a problem in Microsoft Exchange Server
versions 4.0, 5.0, and 5.5.

MORE INFORMATION
================

After Daylight Savings Time takes effect, messages set for delayed delivery, on
April 15, may be sent an hour earlier than expected. For example, if you send a
message to be delivered on April 15 at 4:00pm, the message is delivered at
3:00pm, instead of 4:00pm. The opposite behavior may occur on October 15
(messages sent an hour later than expected) when Standard Time takes effect.

If the requested delivery delay is less than one hour, the message will be sent
immediately. For example, assume it is currently 2:30pm on April 15 (DST). Send
a message that is to be delivered at 3:00pm. The message is delivered right away
(within a few minutes), instead of waiting until 3:00pm.
