Microsoft Corp. unveiled a revamped, Facebook-friendly version of its free, online email service in an attempt to reverse market share losses to Google Inc.'s fastgrowing Gmail. The world's largest software company is renaming its Hotmail service Outlook, giving it a sharp new look, social network links and new features for handling the tide of junk and mass mail that swamps many users. Hotmail was still the world's largest online mail service as of June, according to the latest comScore figures.
