Q: My calendar syncs (Outlook) but I get duplicate entries and. Originations. How can I prevent this?
I'm not sure if this will help, but check your sync settings in iTunes - there's a small-print warning that if you've chosen to sync with iCloud and teh computer,"This may result in duplicate data showing on your device".
