When using Powershell to set Out-of-Office in Exchange 2007 (e.g.), do multiple commands containing -StartTime and -EndTime add to some internal list that Exchange maintains or does each successive command replace the previous command?
For example we have a staffer who is only in the office Tuesdays and Fridays. We'd like to set up Exchange to send an Out-of-Office message to all internal senders on those days when he's not in. How is this best done?
