I want to setup corporate sync on my DroidX and it appears to work until I try to get email.

My office uses Microsoft Exchange.

I think I need to set up VPN to do this? (not sure, I know I have to use vpn to make outlook work if I'm not on the network)

Which VPN selection should I use? We are using a really old Cisco VPN concentrator that I don't know much about, with a Microsoft shop for pretty much everything.

Any help will be much appreciated...
