Microsoft will launch Office 2010 and SharePoint 2010 May 12, offering the platforms to businesses roughly a month before consumers. With that release, Microsoft hopes to maintain its dominant market share in the productivity segment despite upcoming challenges from cloud-based applications such as Google Apps.

Microsoft originally released the beta versions of Office 2010, SharePoint Server 2010, Project 2010, Visio 2010, Office Mobile 2010 and Office Web Apps at the Professional Developers Conference in November 2009. As with its ramp-up to Windows 7, the company expected that a wide beta test involving millions of users would help it tweak and improve the platform before launch.
