First let's discuss what is a Room List ?
This has been built in Exchange 2010 in combination with Outlook 2010 so that users are able to find the Rooms with ease. You can create a List of Rooms on Exchange server & than thru outlook use Room finder as shown below to find the available Rooms.
Now let's check how to create Room List --> Log on to Exchange Management Shell :
To create list run below command: (Same command we use to create Distribution Lists but this is with an option - RoomList)
New-DistributionGroup -Name “Room List Name” -OrganizationalUnit “OU Path” –RoomList
Example: New-DistributionGroup -Name “ConRms Test” -OrganizationalUnit “labtest.com/Exchange/DistributionLists” –RoomList
Room List is now created, we need to add Rooms to the list same as we add members to the distribution Lists.
To add single room:
Add-DistributionGroupMember -Identity “Room List Name” -member “Room Name”
To add multiple rooms:
Create a .txt file and Put the rooms in .txt file then run below command
Get-Content <Path of .txt File>| Add-DistributionGroupMember -Identity “Room List Name”
Now users can use outlook & search available rooms by using Room Finder functionality.
You can also convert the existing distribution list to Room List.
Set-DistributionGroup -Identity "Distribution List" -RoomList
