| | Fix double calendar entires or wrong date
Yes, there is a solution.
First, synce your device. Second, from the Desktop Manager, configure your sync so that the calendar sync is diabled (so that when you sync in the future it will not talk with Outlook).
Next, from the Desktop Manager, select back-up and restore feature. Highlight "calendar" on the ***right*** side of the dialog boxes. Delete it. When the progress box disappears, wait for the device to finish actually wiping the calendar appointments clear. This is aupposed to wipe out all calendar items.
Now check your device. Odds are, a "problem" date or appointment will arise. An appointment (or series of) that did not delete via the Back-up & Restore delete process...it could also be an invisible data error. If problem appointments exist, delete them in Blackberry. Repeat until the problem appointments are gone.
Now, reconfigure the sync settings and bring configure them to sync Outlook. Now sync your device. When done, do a battery pull.
