CAUSE

Event 12002 is a generic IMAIL error. This error event may appear if a user tries to access an e-mail message that has become corrupted. Exchange Server logs this error during typical operation, even if the diagnostic logging level is set to None on the Exchange server. Therefore, the application log on your Exchange server may contain many of these events.
