Office 365 – Room Lists

Create Room List Distribution Groups

New-DistributionGroup -Name “Name of Room List” –RoomList creates a new Room List Distribution Group using the cmdlet’s minimum required parameters for a Room List Distribution Group. If you don’t specify any additional parameters, then they will be set for you.

You may want to take control of your recipient object’s attributes by using additional parameters, e.g. –Alias, –DisplayName, –PrimarySmtpAddress, etc. You can find a full list of available parameters at TechNet New-DistributionGroup: Exchange 2010 SP1 Help.

Add existing Room Mailboxes to Room List Distribution Groups

Add-DistributionGroupMember –Identity “Name of Room List” –Member “Name of Room Mailbox“adds Room Mailboxes to Room List Distribution Groups. It requires that you specify the Room List Distribution Group using the –Identity parameter and the Room Mailbox to be added using the –Member parameter.

You can use the DisplayName, Identity, PrimarySmtpAddress and various other values with the –Identity and –Memberparameters. You might find it helpful to list them.

The following command will list the Room List Distribution Groups.

The following command will list the existing Room Mailboxes.
