With this development, those who use Office 2008 will still be able to do so, but will not be able to get any official support for the program from Microsoft. With its Mac Business Unit, Microsoft has maintained a dedicated development team for its Mac software which has spearheaded development of Office 2004, 2008, and the latest 2011 and 365 offerings. Office for OS X has been a staple in integrating OS X systems with many work environments that rely on Microsoft's popular office productivity suite. Microsoft announced today that it will end support for Office 2008 for Mac on April 9.
