We recently had a server that we put a re-load of SBS 2003. We made no changes to our DSL router, we are running exchange email and internally everything works fine. However we have three people that connect using outlook express from external offices as they are on the road all the time. Since the reload, they cannot download their email. They are not able to connect to the exchange server. I have asked them to use OWA but habits and seniority are defeating me. I did check the Microsoft Exchange POP3 and it is running. Any help would be greatly appreciated, I'm running out of excuses as to why i don't have it working.
