I am looking to purchase an exchange server. I want to make sure it has all the capabilities that I need. I have one corporate headquarters, and ten branch offices. Can I use one exchange server at the corporate headquarters, and have the branch offices also use that server for thier e-mail server via outlook. If so what type of line do I need, do I need a static IP address and what type of cost am I loooking at. I currently have 60 employees using a pop3 email server hosted by an outside company. Is exchange the best way to go?
