When running the Exchange Time Zone Update tool, or the Outlook Time Zone update tool, issues may arise with Resource mailboxes. There are two methods of managing Resource mailboxes. The first method is using the Auto Accept Agent. The second method is by implementing Direct Booking using Outlook's Resource booking functionality.

The Auto Accept Agent is installed and configured on the Exchange Server where the resource mailbox resides. The following workarounds can be used to mitigate problems with the Time Zone Update tools.

UPDATE 3/1: We have consolidated the listed workarounds below to the list of workarounds that will give you the best results only.
