So, I use Outlook to sync my contacts and calendar. Never had problems before. But now when I sync, it duplicates the appointments on my BB that I originally entered into it, but not on my calendar in Outlook. If the appointment originated from Outlook it does not duplicate it. Any ideas?
From Desktop Manager, delete the calendar, then re-sync. If this does not work, try a battery pull. You may have to delete the duplicate appointments and re-sync as well if the above does not work. Good luck!
