so I have been using the office2016 for a year now and I try to update my office 12016 to office365 but it never happened. recently shaw the new office365 feature which is great. So I go to the setting and try to update my 2016 but it did not work. So I go to the Microsoft office home download office 365 free and installed it. After login to the admin portal I now happily us ethe office 365 all feature.
