I am using Windows XP Pro with Outlook Express 6.0 as an email client. I am about to make some equipment changes and reinstall the OS. Which files do I need to backup so that I do not lose my messages and address book? When I tried to "export" the files, it told me that it could not be done. Further investigation revealed that I needed Windows Messenger or Outlook installed for this function to work. Sure enough, installing Outlook 2000 enabled me to export the files from Outlook Express. But there was one problem: I could not import them back into Outlook Express (I tested it on a second computer) and had to use Outlook 2000. I *guess* I could use Outlook 2000 as my email client in the new configuration, but I'd rather not. So, which files do I need to backup in order to save my messages and address book to use in Outlook Express? Would the "Files and Settings Transfer Wizard" do it?
