I'm testing Zimbra 5.0.3 with a Treo 650 (1.05A + VersaMail 3.5 + ActiveSync patch). Email does not automatically show up ("push"). It will show up if the "sync" button is manually pressed. Treo AutoSync is configured as "When Items Arrive" and the user account has "Zimbra Mobile" checked.
Any ideas why email doesn't push ?
