Microsoft has confirmed that there is a problem in Microsoft Office 2004 for Mac Service Pack 2 (11.2.0) that could cause data loss. This data loss might occur when Microsoft Entourage 2004 for Mac tries to synchronize with a Microsoft Exchange Server mailbox that was moved to a different storage group on the server that is running Exchange Server. This problem only affects versions of Entourage 2004 that have been updated with Office 2004 for Mac Service Pack 2 before a mailbox move.

To resolve this problem, obtain Microsoft Office 2004 for Mac 11.2.1 Update. To obtain this update, visit the following Microsoft Mactopia Web site:System administrators typically perform mailbox moves as part of Exchange Server administration and storage management.
