For the emails, use Windows Explorer to search for any files with the extension .dbx, eg there should be files called inbox.dbx, outbox.dbx, sent items.dbx etc. Then in Outlook Express click on Tools - Options - Maintenance - Store folder. If the location is the same as the dbx files you found then your friend may have lost the emails. If, however you find two sets of dbx files of the same name but in different locations then you can simply copy the set not in the place revealed as the Store folder and past them in there. I hope this makes sense!
