we just upgraded our GMS v2 to v3. Everything was working fine with v2 but now when users sync no new mail and calendar items are synced from gw to gms.

If I send a mail or make an appointment on the phone then this will be synced to gw, but all changes made in gw are not synced back to phone.

If I delete the user from gms then it will sync everything accordingly once but only once, all new mails and calendar appointments made in GW after that first sync is not syced over to phone :(

Any clues what could be wrong?
