Outlook Web Access Calendar availability gets "You don't have permission to perform this action"
Have any of you seen this or have a solution for it. In OWA users are not able to see the availabiltiy of other users calendars or even their own for that matter. When you go in and create a new appointment then click the availability tab you get "you don't have permission to perform this action". I'm assuming this is some kind of IIS Permissions issue since there are absolutely no problems when any user uses their outlook client for scheduling appointments.
