I am anticipating purchasing Windows Small Business Server 2003 R2. I understand that it comes with Exchange 2003. Currently, my office uses Microsoft Outlook with a POP3 account for email. I would rather be able to have our own Exchange server to be able to take advantage of shared folders and calendars, althought this is not the only reason for needing SBS 2003. We currently have a DSL internet connection. We don't have our own public, static IP address. Is it possible for my office to use Exchange 2003 in this setting?
