I'm using desktop manager 4.5 and have always been able to sync my calendar with my curve but have never been able to sync emails. When I go into the sync page, the top icon which sets settings for email sync is grayed out and can't be selected. Verizon was no help but seemed to think the Outlook 2007 didn't play nice with desktop. Does anyone know how to make this work? If it won't work, which email programs are you using?
