How do I set up Exchange ActiveSync with windows mobile and or Palm handhelds. I created a ActiveSync policy and linked it to a user enabled for ActiveSync and attached the policy to the user, and obviously tried to connect him and it failed. Do I need to be running Outlook 2007, are there any ports that need to be opened, and once it syncs do you still need to connect to your PC via USB in order to retrieve mail in the future, basically would push technology work here?
