<div class="symptoms_section">

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.

<div class="cause_section">

CAUSE
The Microsoft Exchange message transfer agent (MTA) service does not recognize the change from Standard Time to Daylight Saving 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.

<div class="workaround_section">

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:


 * From the message window, select Properties from the File menu.
 * Click Send Options.
 * Click the Microsoft Exchange Server tab.
 * Under Send This Item, select the appropriate number of minutes, hours, days, or weeks.

<div class="status_section">

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

<div class="moreinformation_section">

MORE INFORMATION
After Daylight Saving 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.
