Automatically Removing calendar items from a resource calendar

I have set up several conference rooms as scheduled resources. All meetings
are accepted and added just fine as well as any meeting moves, adds and
changes. The issue I have is when a meeting is canceled, the calendar show
the meeting is canceled but the event is not automatically removed from the
calendar of the resource. I have to go in manually and remove the event from
the calendar. Is there a way to have this done automatically? Any help or
info here would be greately appreciated.

Thanks
