Hey all, another call for help

I use outlook and one of those messages popped up like "do you want to arcive old items" I didn't read it through( dumb i know). It made another set of personal folders. Now everything that I had is in the old set, contacts etc. and all my mail goes to the new set and my palm syncs to the new set. Does anybody know what I might have done or how to remove the old set. So I can sync back with the old set.

Thanks for any input
