Microsoft is strengthening the presence of clouds with cloud suite Office 365 and believe that they have a lot to offer to businesses than what Google has with the application of their own online. Office 365 came out in May, with applications like Exchange, SharePoint. While denying that Office 365 was expected to "fight" with Google's online applications, said Eron Kelly, director of marketing for Microsoft Business Online Services, said Microsoft already has enterprise-class users Microsoft after trying to use Google Apps.

The application of the online search giant lacks many important capabilities, such as Access Trust (delegate access - allowing users to let others manage your calendar), directory integration (directory integration). However, Google rejected his assertion Kelly. "The truth is that our business is speeding up, and save percentage of our users are actually greater than 90%," spokesman Andrew Kovacs said of Google. "More and more companies are turning to Google (such as Virgin America) rather than to Microsoft." Unlike BPOS cloud services (Business Productivity Online Suite) before Microsoft, Office 365 will have the latest version of Exchange, SharePoint, Lync media servers, client applications and rich web of Office.
