Stop resource calendar keeping attachments?

[NickFerrar]

We have automated resource bookings here for meeting rooms that work fine. The only issue I get is people often include attachments for the meeting when making a booking (as the meeting request goes to delegates as well as the resource). The problem is the resource mailbox is filling up with all these attachments in the calendar (the actual Inbox is empty) which aren't of any use (delegates received their own copy).

Is there a way to just have the resource mailbox accept and process the request but not save the attachment in the calendar booking?
