Microsoft said today that the preview was the biggest Office for Mac beta ever, with over 100,000 pieces of feedback submitted to help make the new programs even better. But today, the new generation of Microsoft's productivity applications exited the preview phase, with the official launch of Office 2016 for Mac in 139 countries and 16 languages. Microsoft launched the first public preview of its Office 2016 suite for Mac earlier this year, and has continued to improve it with regular updates.
