Microsoft ( MSFT) is trending as the company begins its push to increase users of its Outlook.com email service. The final version of Outlook.com, which has been in preview since July 31, is being released Tuesday. It works on Windows and Apple ( AAPL) machines as well as with an app for Google's ( GOOG) Android mobile operating system. The new Outlook includes the ability to send large files in a singe email, address books that automatically update contacts with information from Facebook ( FB), Twitter and LinkedIn ( LNKD) and fewer ads than Hotmail.
