SYMPTOMS
========

The Exchange Server information store may stop responding (crash) and produce a
Dr. Watson log and a User.dmp file with the following call stack:

  

  FramePtr  RetAddr   Param1   Param2   Param3   Function Name

CAUSE
=====

An IMAP user has sent a command that the information store does not process
correctly. The following command may cause this issue:

  007H FETCH 1 (INTERNALDATE RFC822.SIZE FLAGS ENVELOPE BODY UID)

NOTE: The 007H and the 1 following the FETCH command may be different depending
on conversation key and the message being accessed.

You can configure the IMAP protocol in the Exchange Server Administrator program
to allow Rich Text Format (RTF). This setting enables the IMAP protocol to
encode any OLE-embedded objects into a TNEF stream. When the preceding command
is given to the IMAP service to retrieve a message with an embedded OLE object,
such as a Clip Art picture, the preceding command may cause the store to crash.
When the preceding command cannot correctly encode the OLE object into a TNEF
stream. The preceding command works correctly when the setting to allow RTF is
not set in the Administrator program.

RESOLUTION
==========
