Office 365 -- OneDrive Use in Linux
Linux Users Have to Use OneDrive through the Office365 Web Portal
Linux users will have to use OneDrive through the Office365 web portal at https://portal.office.com, and then click "OneDrive."
This has been tested in Firefox in Linux Ubuntu 16.04 LTS, and it works fine there, but no other types/flavors/versions of Linux have been tested yet.
You can edit Word and Excel and PowerPoint files directly in your internet browser through the Office 365 web portal, or download/open those files in LibreOffice, edit them, and upload them again to the Office 365 web portal.
You cannot download Office 2016 or Outlook 2016 or OneDrive and use those applications outside of your web browser, however, in Linux.
