en Passant not letting life just pass on by

Microsoft has an Auto-Accept Agent (or AAA) that can be used on Exchange 2003 servers to process incoming meeting requests to resource mailboxes. Simply send the resource an invitation and within 10-30 seconds, the room will respond back with an acceptance or denial of your request.

In my office, we have over 60 different resources that can be booked online. These resources (including conference rooms, laptops and LCD projectors) can all be scheduled via Outlook and Microsoft Exchange, using Microsoft's latest Auto-Accept Agent. The main draw back is that you can't really tell who has what room for how long.
