XP Office outlook personal folders - duplicates!

[tom]

Through some technical glitch, i lost all my personal
folders months ago - all emails, contacts etc.
After some fruitless weeks of revovery efforts, i simply
started all over.

now, the original set of personal folders, all of them,
have reappeared and are fully accessible.

i need to know how to merge all the email folders,
contacts, etc, but since XP office does not appear to
contemplate this possibility, i am unable to find hints
on how to merge.

Any ideas??
Thanks.
