Anybody know how to clear the calendar entries on the BB, without reloading the entire software back on the BB. I am on a BES, and when you go into Backup and Restore (Advanced), the option to "clear" Calendar and pretty much almost everything else is greyed out.

Any other way ??

If you updated your calendar on your desktop, then did a reconcile, would that work?

Yes, but I'm trying to find a way to clear all entries from the BB and have the BES reset up everything again. I currently have recurring appointment issues where I just need to wipe out the calendar and have it sync from scratch.

Go into PIM and change the calendar to Outlook instead of wireless sync. Then go back to backup/restore and you will be able to clear the calendar.
