I created a room mailbox within Exchange online and now on portal.microsoftonline.com the room shows as a user. If I filter the list to show "unlicensed users" then this room shows up.
Do I need to assign the room a license? Is there a different setting I should use to stop them showing up in the list of users?
I understand that you create a new room mailbox, when you filter ‘unlicensed users’ this room shows up.
1.You don’t need to assign this room mailbox a license.
2.When you create a new mailbox on Exchange Control Panel (ECP), there will be a user account created automatically on the Microsoft Online Portal (MOP).
I want to check if your issue has been resolved.
