I don’t use Outlook Express personally, but I recently rebuilt my father-in-law’s PC and imported his settings from the old disk. I didn’t have a clue where Outlook Express stored its data, but came across an article on the iOpus website about backing up Outlook Express. The old system was non-functional, so I didn’t follow the whole article, but it gave me the information I needed to find all the .DBX files with the mail data and the .WAB address book file.
