“Your administrator has made a change to your mailbox. Please restart.”

This message will be a thing of the past with Exchange 2013, kind of like 8-tracks and cassette tapes.  There have been some significant changes in Exchange 2013’s client access role.  RPC is no longer a supported direct access protocol.  What this means is that all Outlook connectivity must take place using RPC over HTTPS aka Outlook Anywhere.  This means we no longer need the RPC client access service on the Client Access Server.  Also we no longer need namespaces that would normally be required for a site-resilient solution.  Outlook clients no longer connect to a server FQDN, Outlook now uses AutoDiscover to create a new connection point comprised of mailbox GUID @ and UPN suffix (271d1d81-62c1-430e-a33c-d798dda61231@concurrency.com).  This change will nearly eliminate the unwelcome message of “Your administrator has made a change to your mailbox. Please restart.”
