If you require delegates to approval all room bookings in Exchange 2010 and you have the following two settings set to True then rooms will automatically be approved
- AllRequestOutOfPolicy: True
- AllRequestInPolicy: True
To require that rooms are approved by the delegate regardless of when the room is booked set AllRequestOutOfPolicy to False.
These settings require that AllBookInPolicy is False and that BookInPolicy and RequestInPolicy are both null.
