Microsoft Schedule+ is a discontinued time management app developed by Microsoft. After discontinuation, most of its functionality was incorporated into Outlook 97. It was originally intended as a companion to Microsoft Mail, but was later shipped with Exchange Server 5.0, Microsoft Office 95, Exchange Client and Windows Messaging. The "Outlook Calendar" that was part of Outlook for Windows 3.1 and Macintosh versions before 9.0 was actually a new version of Schedule+. After discontinuation, it was with all versions of Microsoft Office up to Microsoft Office 2003, although it is just to support conversion from Schedule+ 1.x.
The first version of Schedule+ was released in 1992 for Windows 3.0 and the classic Mac OS. Versions 2 through 6 were skipped, and the next version became version 7, released in 1995 for Windows 95 and Mac OS. Version 7.5 was included with Microsoft Office 97 and later.
