I have set up a Room Resource mailbox on Exchange 2013 and am trying to get the calendar to display in OSX's calendar app. I have granted free/busy permissions to Group A and set the default to none and anonymous to none.
User A who is a member of Group A on OSX 10.8.5 can see the room resources displayed in Calendar similar to here.
User B who is also a member of Group A on OSX 10.8.5 does not get a list in Calendar. User B can access the calendar using Outlook 2011.
Users C through Z are also like User B.
Is there some special check box I am missing to get it working for Users B through Z?
