XCON: MTA Mishandles Deferred Delivery Messages After Daylight Savings Time Changes

ID: Q225345

The information in this article applies to:

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

A supported fix that corrects this problem is now available from Microsoft, but it has not been fully regression tested and should be applied only to systems experiencing this specific problem. If you are not severely affected by this specific problem, Microsoft recommends that you wait for the next Microsoft Exchange Server version 5.5 service pack 3 that contains this fix.
