XIMS: Information Store Stops Responding from an IMAP4 Download Because of Pointer to a CMDBMessage (278487)


The information in this article applies to:

  • Microsoft Exchange 2000 Server
This article was previously published under Q278487

SYMPTOMS

When an Internet Message Access Protocol, Version 4rev1 (IMAP4) message that contains a NULL pointer to a CMDBMessage is downloaded, the information store may stop responding.

CAUSE

This problem can occur if an embedded message is being fetched through IMAP4. The message is marked dirty when the GetBodyOffsets() function calls the RefreshMime() function. IMAP4 attempts to re-render the message, but there is no CMDBMessage to refresh because the message is an embedded message. The code needs to check for the presence of the CMDBMessage before the code tries to re-render the CMDBMessage.
