XADM: Duplicated Message Received with Information Store Post-Service Pack 3 Hotfix (274200)



The information in this article applies to:

  • Microsoft Exchange Server 5.5 SP3

SYMPTOMS

After you install any post-Exchange Server 5.5 Service Pack 3 (SP3) information store hotfix (between build 5.5.2652.68 and 5.5.2653.16), you may receive duplicate messages when the message was originally sent to you or to a distribution list that includes your mailbox.

CAUSE

Any information store fix after build 5.5.2652.68 has been changed to use the Internet ID globally unique identifier (GUID) instead of the Instance ID to track message duplication. The local delivery pointer is not initialized correctly after the modification.
