My D2G doesn't stay synced especially if the phone is in standby sleep mode with the screen locked. I've tried all manner of settings as well as touchdown, stock email app, and Improved Email app and they all behave similarly. It will require a reboot or battery pull to get the emails going again if the phone has been inactive for a while. Owners of other Motorola models also seem to have this kind of problem with email just want to see other corporate users experiences with the D2G.
