Outlook Express

Outlook Express is a discontinued email and news client included with Internet Explorer versions 4.0 through 6.0. As such, it was also bundled with several versions of Microsoft Windows, from Windows 98 to Windows Server 2003, and was available for Windows 3.x, Windows NT 3.51, Windows 95 and Mac OS 9. In Windows Vista, Outlook Express was superseded by Windows Mail, then again by Windows Live Mail as separate software. Microsoft Entourage (up to the 2008 edition) and then Microsoft Outlook (in Office 2011), sold as part of Microsoft Office for Macintosh, has replaced the Macintosh version.
