Hi,We upgraded to Exchange 2007 SP2 and Powershell 2.0 this weekend and I am having problems gaining access to a calendar. I ran:add-adpermission -id north_room -user me -accessrights genericallThe command completes successfully but when I use Outlook to open the Norht_room calendar it reports I don't have access and asks whether I want to request "north_room" grant me access. North_room is in another domain in which I am not an admin but I am an Exchange Org Admin.What am I missing?

To grant full access: ( thats what you are looking for yes?)http://technet.microsoft.com/en-us/library/aa996343(EXCHG.80).aspxAdd-MailboxPermission "Mailbox" -User "Trusted User" -AccessRights FullAccess

You're right. I don't know why I got hung on this add-adpermission bit. Time for some coffee.Thanks
