we only allow our users to connect in with a VPN client in order to send email when they are not in the office.
they do this if they decide that using the webmail doesn't give them what they need.
This is how I have it set up also. Webmail is available for all and if for some reason they need to connect with outlook then they have to go through the vpn. -- don't get 2 close 2 my fantasy
