Hi Murat,
Maybe you can help clarify something I've noticed with Outlook 2007/Exchange 2007 and resource booking.
Right now I believe we're still using the old direct-booking system, because if I take away write-access to the rooms' calendars from users, they can no longer book a room.
However, the benefit is that if they try to book a room that's already booked, they get a dialog pop up ("The resource is already booked for that time" or something) when they click "Send" on the meeting request. Outlook won't let them send invitations if the room is already booked.
As I understand it, the newer system with the "auto-accept agent" for rooms meens that if the room was already booked it *waits for the invitation* and then sends back a "decline" message. That means that you could have already invited 20 people to your meeting, and only then realise that the room was double-booked. You'd have to send out alteration notices to all the invitees.
I know that simply checking the scheduling assistant tab in the meeting request form could prevent this, but my users wouldn't always do this. Having the "already booked" dialog prevent them from sending the invitation seems like a better solution.
Can we have both? Can I somehow restrict write-access to rooms' calendars, but also get the "already booked" dialog if a user tries to double-book a room?
Cheers!
