I've configured one of our conference rooms as a Room resource in Exchange 2007. Someone can create a meeting request and select it to be used during their meeting. If there is no conflict in scheduling, they get the ACCEPTED: email from the Room's mailbox. If there is a scheduling conflict and someone has already reserved the room, they get the DENIED email from the Room's mailbox and a description of which meeting is conflicting with theirs.
My question is, is it possible to just ALERT the user when they are creating the Meeting Request in Outlook, before the meeting is scheduled? I would like for them to select the Room resource in outlook, and when they try to send they get a error saying the Room is already in use at this time and to choose another (or communicate with original meeting organizer). This way they can either change their meeting time or choose another room.
Is this possible? Thank you!
