I have what should be a very simple configuration, a single Exchange 2010 SP2 server and single TMG 2010 SP2 server with all workstations running the Forefront TMG client 7.0
When users try to configure there "Out of Office" settings they get the error message - "Your Out of Office settings cannot be displayed becuase the server is currently unavailable".
If I disable the TMg client and remove the proxy setting from Internet Explorer then the "Out of Office Assistant" works.
What is the best way to resolve this or what are the recomened setting for Exchange 2010, IIS 7 and Forefront.
I would have thougth that as all the products are Microsoft and its a common and simple scenario that it would all just work :(
