For OE it's simple. Use OEBackup.

For OL, I have no idea where the counters are stored.

Everything is fine until I decide to format my C:\ and clean-install
Windows
XP again. I then setup Outlook Express to use D:\Outlook Express\ folder
and
it says it detected existing files and prompts me if I want to use them.
I
say yes. However this doesn't work and Outlook Express starts
downloading
all my mail again.

I setup Outlook to point to D:\Outlook\outlook.pst and it starts
download
all my mail again.


What is going on? Is this Outlook bugs?



No - it's because the mail counters for both apps are held in the
registry,
which of course is completely fresh after the re-install, NOT in the
respective data stores. Whether you can find, export and re-import those
registry keys I don't know...
