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:

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.
