XFOR: MIME and UUENCODED Messages Cause Store Conversion Error

The information in this article applies to:

• Microsoft Exchange Server version 5.0

SYMPTOMS

A message sent from an Internet Mail client to a computer running Microsoft Exchange Server may cause the information store (IS) to generate a conversion error and return the message with a non-delivery report (NDR). It may also cause the IS service to terminate.

CAUSE

This problem can occur when a message received by the IS from the IMAIL client is using a foreign character set in the message that is also supported by an installed code page on the Microsoft Exchange Server.

The message comes in, and Microsoft Exchange Server calls upon a conversion routine to change the message to MDBEF format. When the conversion routine runs, it checks to see the installed code pages on the server and incorrectly uses one that matches the client.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.0. This problem was corrected in the latest Microsoft Exchange Server 5.0 U.S. Service Pack.
