I was able to get ActiveSync 4.2 to sync my ACT! v6.0 contacts to my Treo 700wx and the contacts showed synchronized in ActiveSync, but were missing on the Treo. I have seen similar posts, any suggestions?
Oftentimes the problem is simply that the contacts are filtered on the pda and, if you don't assign categories to your contacts, they don't appear when the application is opened.
To check, simply open Contacts and set the drop-down (top left-hand side of the screen) to All Contacts.
