I too have a problem with pass thru, but, only at home. When connected at work with a data cable, I am able to sync with exchange server thru AS. When I connect to my home PC via the cradle at home, it will not sync to exchanbge server thru AS.

Home setup:
Windows XP Pro
Cable modem
No router
Windows firewall on

Is it possible to sync with the exchnage server thru AS on my home PC?
