I'm not real familiar w/ the ISA server but I'm assuming it allows some type of VPN connectivity. I believe I remember reading something recently about ISA having some "secure" publishing feature for outlook. That would be a question for the ISA folks.

However opening those ports blindly to the internet == BAD. Repeat after me... "I will not open up my network to hackers" Since you're using Exch2K, You would have really two options: 1) VPN and 2) OWA. Of course I guess you could do dial-up RAS but does anybody actually still use that stuff? :-) We use a combination of VPN & OWA here at our facility and have a number of users who travel frequently with laptops. Do you have any type of firewall in place besides the ISA server?

What version of Outlook are you using? Thanks!
