We're attempting to setup a few shared calendars in our Exchange 2007 organization, and would like to not use public folders.
I understand the best way to do this and still centrally manage them, is to utilize a Resource Room mailbox and assign permissions to that.
I used the Exchange Powershell to create the Resource Room with a display name of "Workers Schedule" and set it to auto accept meeting requests. I then set 'FullAccess' permissions to the users that should be able to modify, and 'ReadPermission' to those that should only be able to view the calendar.
When I jump on Outlook 2007 with a 'ReadPermission' user, go to File -> Open -> Other Users Folder -> Select Calendar -> Select "Workers Schedule" resource room, I get a message that says I do not have access and to tick a box to send an email requesting access.
Interestingly, if I give that user 'FullAccess' and log back in with that user account, the "Workers Schedule" resource room disappears from the GAL.
Not sure why it's doing this, or what permission I may have missed?
