So since I have no real life and tend to live, breathe and die with MS Exchange I was doing some trolling and found a very handy work around for something that has bothered me in the past. In Exchange 2007 per the documentation if you wanted to set the calendar auto accept settings. this could work very nicely for room resource mailboxes as well.
Now per the documentation you have to run the following exchange management shell..
[PS}> set-MailboxCalendarSettings -id RoomName1 -AutomateProcessing AutoAccept
Those who are resistant to Exchange Management Shell work can use the following steps from within powershell and OWA!
nice work Bharat Suneja!
