I have a work enviroment that is using exchange 2007, with an owa server access. I would like to connect to the IMAP mail server but it is behind the VPN, and it is not compatible with the WM5 VPN. IS there a service or software that can access the owa server and then transfer it to a pop3 or IMAP mail server?

Why not just use the built-into Exchange 2007 Activesync server? No VPN or anything. Just need port 443 (SSL) open to make it work. Heck, it even has user-controlled data wipes if you should lose the device. No need to even bother your IT Department. All you to do to make this work is to install the SSL cert you're already using for OWA.

Why use IMAP or POP when Exchange is so much better?
