I have an Exchange 2010 server setup that serves three separate offices. What I want to do is create three Room Mailboxes for conference rooms to be scheduled, but I want to restrict it so that those respective offices can ONLY see in the GAL the conference rooms for their locations.
For example, my offices are Washington, Atlanta, Chicago. The conference room mailboxes are called DC-conference, Atl-conference and Chi-conference respectively.
I want only those people in the Washington office to see in the GAL the DC-conference room, Atlanta only to see the Atl-conference room and Chicago the Chi-conference room.
How do I do this in Exchange 2010? And can it be done through the EMC? If it has to be done through Power Shell, can you provide me with an example script?
