Microsoft Office 3.0 is a version of Microsoft Office, the second major release for the Microsoft Windows operating system and the third on the Macintosh. Omitting version 2 entirely on Windows, Microsoft released Office 3.0 on August 30, 1992.
Its main components included Word 2.0c, Excel 4.0a, PowerPoint 3.0, and Mail, a network messaging client. Previously, these components were distributed separately for Windows, and it was with Microsoft Office that they were combined as a full office suite. Versions for Macintosh were also updated to Word 5.1, which didn't exist for Windows.
It was superseded by Microsoft Office 4.0.
