Microsoft Office 2003 is a productivity suite written and distributed by Microsoft for their Windows operating system. Released on October 21, 2003, it was the successor to Office XP and the predecessor to Office 2007.
A new Office logo as part of a rebranding effort by Microsoft, as well as two new applications, made their debut in Office 2003: InfoPath and OneNote. OneNote is a note-taking and organizing application for text, handwritten notes or diagrams, recorded audio and graphics. Office 2003 is the first version to use Windows XP style icons and colors.
Office 2003 runs only on NT-based versions of Windows (it does not support Windows 98 or Windows Me).
The core applications, Word, Excel, PowerPoint and Access have only minor improvements, however Outlook 2003 received a significant facelift and improved functionality in many areas, including better email and calendar sharing and information display, search folders, colored flags, Kerberos authentication, RPC over HTTP, and Cached Exchange mode. Another key benefit of Outlook 2003 is the improved junk mail filter. Tablet and pen support was introduced in the productivity applications. Word 2003 introduced a reading layout view, document comparison, better change-tracking and annotation/reviewing, a Research Task Pane, voice comments and an XML-based format among other features. Excel 2003 introduced list commands, some statistical functions and XML data import, analysis and transformation/document customization features. Access 2003 introduced a backup command, the ability to view object dependencies, error checking in forms and reports among other features.
