I'm using Intellisync for GroupWise 7.0.1 and my Treo 680 with the lastest version of its software. Everything syncs fine on the phone itself, and e-mail is working fine on both the PC (Windows XP) and phone. However, the calendar on my PC version of GroupWise has duplicates of most appointments -- as many as four or five at last count, and I just set up GroupWise on the phone a few days ago.
