Auto Delete Of Email Meeting Msg

When planning a meeting for our Boardroom…(which has it’s own PC & Calendar, but is not manned by a person 8 hours/day) we Click ON the Actions Tab, Plan A Meeting, Click on Add Others, select the invitees and click on the Required Tab. Then select the Board Room contact and click on the RESOURCES tab. Everything works fine the Board Room automatically accepts the meeting event and schedules it, but …. how can we get outlook to automatically delete the email that is sent to the board roomInbox AFTER it has been accepted and scheduled. Our Inbox gets so full of unread emails, which are nothing but scheduled meetings and someone has to go in and delete them all manually.

Thank You
