The next version of Microsoft Office will include Office Web applications that will help improve productivity and enhance the desktop experience by enabling people to access, create, edit, share and collaborate on Office documents across multiple devices.

New Web applications for Office were demoed at Professional Developers Conference. The applications are lightweight versions of Microsoft Office Word, Excel, PowerPoint and OneNote that are used from within standard Web browsers. Anyone can use all of the Web, phone, and PC versions of Office to edit the same rich document, switching among them seamlessly with lossless file compatibility.

Office Web applications for Microsoft Office Word, Excel, PowerPoint and OneNote will be available to individuals through Office Live, and to businesses though a hosted subscription and existing volume licensing programs. This new offering will be compatible with familiar Web browsers from Internet Explorer, Firefox and Safari. Microsoft will release a private Technical Preview of Office Web applications later this year. In the meantime, customers interested in learning more about the upcoming beta availability are encouraged to sign up for Microsoft Office Live Workspace.
