There is a new service, called Office 365, is available as an experiment purpose and will be on sale on a subscription basis worldwide next year. Combining some of Microsoft's existing cloud-based services, it will be available through most browsers, including Mozilla's Firefox, Apple's Inc's Safari and Google's Chrome and IE also. That means customers can get access to Office programs like Outlook e-mail, SharePoint websites and simplified versions of Word and Excel without installing software, from virtually anywhere.

The move takes a blow against rival Google, which has had some success with its Google Apps service, which provides a low-cost. For more info, u may link to :
