A nice new feature of Outlook 2010 / 2013 when scheduling a meeting is the Room Finder.
New-DistributionGroup “Meeting Rooms” –RoomList
Add-DistributionGroupMember -Identity “Meeting Rooms” -Member meetingroom1
You will now be able to click the room list drop down box and see it populated with your meeting room list members.
