Currently we used windows 2000 server running exchange 2000 server. (using both outlook 2000 and 2003) We have about 10 people outside who access email via VPN (SonicWALL) never had any problems with it. Recently we added a member server running 2003 server and 2003 exchange server. I have moved the people to this new server and upgraded them to outlook 2003, I do not have a problem out of the office VPN'ing into the server and accessing exchange through my outlook. 1 person who was running outlook 2003 had no problems on the 2000 exchange server but now since he is on the 2003 exchange server he no longer can access the exchange (Everything else on the vpn works fine, he can get into folders on the server but no exchange) another guy who was upgraded from outlook 2000 to 2003 and exchange 2003 is having the same issue. I can take their laptop in the office, connect them to a public IP address on the outside of our sonicWALL and connect in just fine via VPN and access exchange. Any clues anyone? The second guy has tried access from his remote job site as well as his house, both worked fine before, now they dont. Thanks for the help Mell
