I use a non exchange, but activesync and syncml compliant groupware server for email, calendar, contacts, etc. Trying to set up synchronization as an EAS doesn't work. Any suggestions? I am using FirstClass and run their latest sync services (9.1 Build 30). I can sync Blackberry using 3rd party software, iPhones (they have their own iphone client), old palms (via hotsync), and winmobile.
I hope this doesn't become the make or break issue!
