When scheduling a meeting, if using the Scheduling Assistant and Room Finder, selecting Conference Rooms results in a list of all conference rooms but except 1 conf. room .(conf-a room)
If using the Rooms button on the Appointment the Select Room ( conf-a-room) dialog is displayed and it is on there:
not sure why in (conf-a room ) in room finder is not displayed, i checked it is not hidden in address book.
we have on premise AD and is replicated through AAD sync to office 365
any attribute I should check on onpremise AD
