Outlook Express (formerly Microsoft Internet Mail and News) was an e-mail program bundled with Microsoft Windows starting with Windows 98. You could download it onto machines running Windows 3.x, Windows 95, Windows NT 3.51, and Windows NT 4.0. The product was included on Windows 98 up to Longhorn before being discontinued in favor of Windows Mail found in Windows Vista and in some pre-release builds of Windows 7 (though it was purposely broken in later builds) before being reintroduced in Metro language form in Windows 8 and 10. Many people often confuse this with Microsoft Outlook, bundled with Microsoft Office and hence think Outlook Express is a stripped-down version of Microsoft Outlook, however that is not the case as the programs don't share a common code base.
History[edit | edit source]

Microsoft Internet Mail and News was initially released in 1996.
Microsoft Internet Mail and News (2.0)[edit | edit source]
Microsoft Internet Mail and News 2.0 was released later in 1996. The following year, its name was changed to Outlook Express.
Outlook Express 3.0[edit | edit source]
Outlook Express 3.0 was the first version to carry the Outlook Express branding instead of the Microsoft Internet Mail and News branding. This version was released in 1997.
Outlook Express 4.0[edit | edit source]
Outlook Express 4.0 was released in June 1998 and was bundled with Windows 98.
Outlook Express 5.0[edit | edit source]
Outlook Express 5.0 was released in June 1999 and was bundled with Windows 98 Second Edition.
Outlook Express 5.01[edit | edit source]
Outlook Express 5.01 was released in February 2000 and bundled with Windows 2000.
Outlook Express 5.5[edit | edit source]
Outlook Express 5.5 was released in June 2000 and bundled with Windows Me.
Outlook Express 6.0[edit | edit source]
Outlook Express 6.0 was released in 2001 and bundled with Windows XP. This was replaced with Outlook Express 7 in Windows Longhorn, however, in the post-reset builds, it was reverted back to Outlook Express 6, and then eventually Windows Mail.
Outlook Express 7.0[edit | edit source]
Outlook Express 7.0 was seen in pre-release builds of Windows Longhorn (Vista), which would indicate that Windows Vista was to have Outlook in the final RTM build, however, in 2005 Outlook Express 7.0, along with the WinFS feature heavily needed for it was both scrapped and replaced with Windows Mail, which has a similar layout. You can find Windows Mail in Windows 7 pre-releases, though in later builds, it was intentionally broken. Windows 7 got Windows Live Mail instead. Windows Mail should not be confused with the Windows Mail present on 8 and 10 systems.
Replacement[edit | edit source]
As stated above, Outlook 7.0 was scrapped from Windows Vista and replaced with Windows Mail. This was included in many Windows 7 preview builds, though in later builds, it was intentionally broken. This was replaced in the final RTM build with Windows Live Mail, also downloadable for Windows XP, Vista, 8, 8.1, and 10 machines. In Windows 8, 8.1, and 10, Microsoft reused the Windows Mail name for a Metro language mail app.
