Microsoft Office 2003

Microsoft Office 2003 (codenamed Office 11) is an office suite developed and distributed by Microsoft for its Windows operating system. Office 2003 was released to manufacturing on August 19, 2003, and was later released to retail on October 21, 2003. The Mac OS X equivalent, Microsoft Office 2004 for Mac was released on May 11, 2004.

New features in Office 2003 include information rights management; new collaboration features; improved support for SharePoint, smart tags, and XML; and extended use of Office Online services. Office 2003 introduces two new programs to the Office product lineup: InfoPath, a program for designing, filling, and submitting electronic structured data forms; and OneNote, a note-taking program for creating and organizing diagrams, graphics, handwritten notes, recorded audio, and text. It also introduces the Picture Manager graphics software to open, manage, and share digital images.

With the release of Office 2003, Microsoft rebranded the Office productivity suite as an integrated system dedicated to information workers. As a result, Microsoft appended the "Office" branding to the names of all programs. Office 2003 is also the first version with support for themes and visual styles, and introduces updated icons. The Office logo was also updated, eliminating the puzzle motif in use since Office 95. Office 2003 is the last version of Office to include the traditional menu bar and toolbar interface across all programs, and also the last version to include the "97 - 2003" file format as the default file format.

Office 2003 is compatible with Windows 2000 SP3 through Windows 7 and Windows Server 2008 R2. It is the last version of Microsoft Office to support Windows 2000 SP3+, Windows XP RTM–SP1 and Windows Server 2003 RTM.

Microsoft released a total of three service packs for Office 2003 throughout its lifecycle. Service Pack 1 was released on July 27, 2004, and Service Pack 2 was released on September 27, 2005. Support for Office 2003 ended on April 8, 2014.
