It will change the query for the All Rooms that is loaded to not include equipment mailboxes.

Am currently on mobile, Will revise as soon as I get behind a laptop.
When you Open-up the "Exchange Management Console" > Organization Configuration > Mailbox > Address Lists

Choose the "All Rooms" > Next

The "Recipients filter" should have the below value:
((Alias -ne $null) -and (((RecipientDisplayType -eq 'ConferenceRoomMailbox') -or (RecipientDisplayType -eq 'SyncedConferenceRoomMailbox'))))

you can use the Preview to see the result which would be listed for the "All Rooms"
