I don't think you can as outlook express stores your emails diectly onto your computer. You can access your emails via the web though without using outlook express. Say you are using AOL or Hotmail or whatever-just go straight to their site and login to your emil. If you need to access an old email and you know that you are going to be away and unable to use outlook express, forward it to another email adress which you can reach from anywhere-such as a hotmail account. I send all of my importannt stuff to gmail for safety, so that I can then access it anywhere. This is safer that OE also as if your pc crashes and you end up doing a reinstall you often dont manage to save your emails from OE.
