How do I replace Microsoft Exchange with Outlook Express in Windows 95?

Microsoft Outlook Express is an e-mail and news client bundled with certain versions of Microsoft Windows starting with Windows 95 OSR-2. It is bundled with the Internet Explorer 4.0 web browser by Microsoft (also bundled with some versions of Windows), and also available as a no-charge download for the classic Apple Macintosh operating system (although not for the newer Mac OS X, where it has been replaced by Microsoft Entourage, which is sold as part of Microsoft Office for Macintosh).
