Enable Auto Processing of meeting requests for room mailboxes

Users with FullAccess to resource accounts can open it via Outlook or OWA.

Users prefer resource accounts to accept or deny requests automatically. For manual processing, the user must be setup as a delegate to that resource account

To enable auto processing from the powershell command line, type:

Set-MailboxCalendarSetting -id mailboxname -AutomateProcessing AutoAccept -AddOrganizerToSubject $False
