I have 2 Droid 1 users experiencing 2 different issues.

My first issue is that when the user posts a new appointment from the mobile to GroupWise, it is sending the event to GroupWise, but it is showing duplicates back on the Droid after the initial sync with GW.

My other user doesn't sync reliably after the initial sync. After the initial sync, the primary email box doesn't sync automatically with GW until I delete an email from within the syncing time period (3 days).

I personally set up any mobile devices to sync and have configured all of the Droids identically, so it shouldn't be a matter of being misconfigured. Both devices are up to date on updates and don't experience the same issues as the other. Log files don't show anything out of place indicating a problem either. What else can I do or check?
