I have a clean installation of Exchange 2010 on a server 2008 r2 with Outlook 2010 (70 users). My problem is that I cannot see the free/Busy scheduler or any appointments in my ressource calendar (meeting rooms etc.). No user has access rights to do so. Auto answer works fine. It is possible to see free/busy from OWA!?
For normal users I have manualy shared the calender, which works fine..
