Hi

I don’t use Outlook Express, but I do use Outlook. Outlook saves all of your emails in a .PST you can either try searching for .PST or have a look in C:\Documents and settings\USERNAME\Local Settings\Application Data\Microsoft\Outlook. You will need to be able to browse hidden folders to navigate here (open My Computer, Click the Tools menu and select Folder options, then click on the View tab and select the ‘Show hidden files and folders’ radio button) These files will not get overwritten if you re-install your application. You can import your emails back into Outlook (should be the same in Outlook Express) by opening the program and selecting File, then Data File Management. Click Add and select the second option (Outlook 97-2002 personal file folder)

I know this is using Outlook and not Express but I hope it helps.
