Hello all, I am pretty new to Exchange 2007 but have been tinkering with it a while now. What i am trying to do is share a resource calendar so users can access them on their outlook clients via "open shared calendar" but not have fullaccess to edit the calendars. I know you can add full access via EMC, and ive tried "Add-MailboxPermission -Identity User -User User2 -AccessRights ReadPermission" but i am not able to open a shared calendar with User2. Any suggestions? All i want to do is have poeple be able to See the resource calander for target rooms w/o the user having access to change them.Thanks for any help.
