" Even though you still have legacy Outlook clients (Outlook 2003 and earlier) in your organization, you dont need to set up a replica for the SCHEDULE+ FREE BUSY or the OFFLINE ADDRESS BOOK system folder. This will be done automatically when deploying an Exchange 2007 Server in a legacy Exchange organization. "

All other "user" public folders have been set up as replicas and are working.
