Convert a Distribution Group into a Room List


Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2

In Microsoft Office Outlook 2007 or earlier, if you wanted to search for a conference room's availability while setting up a meeting, you needed to add all possible conference rooms to the meeting request, and then use Scheduling Assistant to view available conference rooms.

In Microsoft Exchange Server 2010, you can create room list distribution groups to generate a list of building locations so that in Outlook 2010, users can select a building and get information about room availability in that building without having to manually add all the rooms in the building.


In Exchange, you can convert a distribution group to a room list only if all the members of the distribution group are room mailboxes. In addition, after the distribution group is converted to a room list, or after you create a room list, you can only add room mailboxes to the group.
