You are using Office 365 with multiple domains. When you try to add some of the rooms in RealTime Manager, the following error message shows up:

Cause

This occurs because of configuration matter: Room mailboxes are not configured to support auto-discovery. If you check the MAPI access of the mailbox, you can find that it is disabled:

Workaround

To make room auto-discovery work, you should call this command for each mailbox in the Exchange Management Shell:

Set-CASMailbox MailboxName -MapiEnabled:$true

(Replace MailboxName with room email)
