Hello all, I'm new to the forum but see this as a tremendous asset/resource. I have MS Office 2007 Home and Business edition and am trying to share my calendar with a few contractors. What I want is to be able to publish my calendar to live.com, invite specific users to see and accept it, then allow them to make changes to that calendar from their end and have it update on my outlook calendar. Where I am running into a roadblock is that my "Calendar Permissions" buttons are grayed out. I can't figure out how to give someone permission to make changes to my calendar...any suggestions? Thanks!
