Microsoft Internet Mail and News is a freeware e-mail and news client and ancestor of Outlook Express. The version 1.0 was released in 1996 following the Internet Explorer 3.0 release.
This add-on precedes the Internet Mail profile for Microsoft Exchange 4.0 bundled in Windows 95. A version 2.0 was released in the end of 1996. In 1997 the program was changed and renamed as "Outlook Express" and bundled in Internet Explorer 4.0. The executable file for Outlook Express, msimn.exe, is a holdover from the Internet Mail and News era.
