Mailbox determination

Exchange 2010 come replete with 4 mailbox types. 

Equipment
Room
User
Linked

There is not much between them to be honest, the Room mailbox has some extra attributes such as capacity but they are just mailboxes albeit with nice icons. 

The interest comes when the Calendar Attendant is used. 

On a standard User mailbox the attendant does some rudimentary house keeping *yawn* but on the Room and Equipment mailbox the attendant can approve or reject meeting requests.

This is really cool as now the Rooms or Equipment mailbox can effectively manage it's own calendar.  You can have a "real" person own the calendar too for fine tweaking but calendar conflicts can be managed by the organiser, they receive a kind email saying that the room is not avaliable during that time.

If the organiser is sensible it is also possible to add a Room or Equipment mailbox as an attendee of the meeting and use the Scheduling Assistant to see when the Room or Equipment is actually avaliable.

Unfortunately Microsoft have missed a trick in whilst you can search for a "resource" based on the extra attributes, like room capacity, it is clunky (the search and it is possible to jam a room full and the Room mailbox wont query this.  It would be nice if the Calendar Attendant was able to count the attendees (less itself of course) and decide on whether it is a suitable room.  Maybe feeding this back using the excellent MailTips..?

Another annoyance is that you cannot link resources so you cannot link the calendar of a projector to the calendar of a room.  This means you have to add both to the invite to book them.  It would be better to allow either to be booked seperately however the container also books the contained.  MailTips could be used here again to feedback that for an added room whether resources are avaliable.

One step at a time I guess.
