One user uses outlook with the connector with GW8 in the background. He's syncs a HP iPaq in Vista but a strange thing happens where suddenly emails start replicating! Seems random, not tied to time/date etc, but suddenly for no reason one email will turn into 70 or 1 email with turn in 7, all exact duplicates of the other.

I've tried running a gwcheck on his account and that was fine.

Any ideas?
