how to blank out Calendar database

[mlevin77]

I think I have a corrupted Calendar database (my sync over-the-air with an Exchange server works for everything else but now always gets stuck half-way through the calendar sync). How do I completely clear out the Calendar database? It says if delete the Exchange server settings, it will *not* clear my database. I'd be happy to clear them all (email, contacts, etc.) - that's fine too, I'll just re-sync everything. How do I do it? I'm running phoenx06's C&S ROM on a Verizon XV6700.

Thanks,

Mike
