Exchange resources - Auto Accept Agent

For resources such as meeting rooms that needs to be 'invited' to a meeting (or otherwise booked), it is a pain to have to constantly log into an Exchange mailbox to accept/reject invitations - especially if you are tasked with managing a heap of them. Microsoft have a tool to take the hassle out of this, though it is a bit of a convoluted process - see here for more info on the Exchange Auto Accept Agent.
