Question : Exchange 2007 booking a conference room

Is there a way for Exchange/Outlook to not allow a meeting request to go out if the conference room added is booked?

Currently if a user books a Conference Room and Attendee's, the Attendees can accept, and the Conference room can decline, forcing the user to cancel that request and start over.  I'd prefer if the room failed to book it wouldn't allow the request to go out at all.

Answer : Exchange 2007 booking a conference room

Theres really only a few simple ways around this.

1) Train the user to Book the Conference Room First.

Once accepted. Then go back into the Appointment, and then add the Attendees.
Update the meeting. Send Responses Only to Added or Removed Users.

2) Add all staff (Or Selected Staff Members) as delegates of this conference room.
Set their permissions to Reviewer Only

This will allow the staff member to check the conference room first, before making an appointment, to see if its already booked for that time or not.
