You can, at least in theory, import your .dbx files into either Windows Live Mail or Mozilla Thunderbird. I say "in theory," because neither of them successfully imported the .dbx files I tried to import. Your luck may be better than mine. The import tools are easy to find in either program. Or you can view dbx files https://www.viewertool.com/dbxviewer.html This is very simple little program can read Outlook Express.
