Mike Pfeiffer has a nice write up on querying a list of conference rooms in Exchange 2010 using PowerShell.
If you work in an campus type of environment, where you have conference rooms spread out across multiple buildings or physical sites, you may have heard of the Room Finder functionality introduced with Exchange 2010 and Outlook 2010. The Room Finder allows users to easily locate a room resource when scheduling a meeting in Outlook. Instead of users having to scroll through the Global Address List (GAL) or try to guess which room resources are located in a particular location, they can select the appropriate room list, and see all of the available rooms.
Room lists are essentially just a special type of Distribution Group in Exchange. To populate the room list, you simply add one or more resource mailboxes to the group. After you’ve defined several room lists, you’ll probably get to the point where you need to generate a report listing all of the room lists and their associated resource mailboxes. The key to generating a report is to simply query the members of each distribution group that are designated as a room list.
