I have set up a room calendar in Exchange 2007 called "Boardroom". I also created a mail-enabled security group called Boardroom Calendar Users so that I could centrally manage the permissions. The Boardroom Calendar Users group has permission to view, add events, and delete own events. I applied the permission by going into Outlook and adding the group to the calendar permissions, since I have full access. I have two problems hanging me up. 1. The permissions granted to Boardroom Calendar Users are not being correctly applied to the calendar. A member of that group cannot add or delete thier own events, although they can view the calendar. 2. When I use a meeting request to add an event to the calendar, everyone in the Boardroom Calendar Users group gets an invitation to the meeting, which is not what I want to happen. What dumb thing am I missing?
