I've searched for this, but wasn't able to find the answer (that I know must be out there). How do I delete all calendar data on my BB? I then will set my software to first sync status and populate the BB. Thanks!

If you are using Outlook to sync, i would delete in Outlook because it is alot easier then in the BB.

Thanks. I am not using outlook to sync (Mac). I guess what I'm saying is that the data is screwed up on the BB, but I've cleaned it on the desktop.

Launch your Desktop manager
Go to Backup and Restore
Click on Advance
Find the Calender database by scrolling down
Select it and press the Clear button

Done
