XCLN: Unable to Display Outlook Calendar Folder After Move Mailbox

When you use an Exchange or Outlook client to view another user's server- based folders, you may not be able to access the Outlook Calendar folder. You may receive the following error message: In addition, delegate features may not work or may fail intermittently.

To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For more information, please see the following article in the Microsoft Knowledge Base:

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. This problem was first corrected in Exchange Server 5.5 Service Pack 2.

This condition may exist after moving user mailboxes from one server in the site to another using move mailbox. This condition will occur even when the client permissions are correct. The above problem can also be seen without using MoveUser. In order to apply this fix, each client computer experiencing the above problem needs the updated Emsmdb32.dll file.
