> Is it possible to auto respond to emails using Exchange 5.5? You can create one using the rules wizard, just select "have server reply using a specific message" for the action. Be advised that this can cause mailing loops with other auto-responders or out-of-office messages. If you look at solutions that work from outside of Exchange (using POP/SMTP) then you have a lot more options. This product looks very interesting: http://www.autoreplying.com/
