Win2000 – Importing Mail from Win98SE

I am installing Window 2000 and have back up all the relevant files for my Outlook Express 5.5 Mail folders and my address book (and Favourites, My Docs. etc) backed up from Windows 98SE.

After installing Win 2000 (clean install) and setting up IE and Outlook X, I can’t find where the Email-relevant files are saved, so that I can replace them with my backups.

Is it possible?
