There are ‘Office Online’ plugins for both the Google Chrome and Microsoft Edge browsers.
These extensions sound great and, from the hype, seem amazing but are little more than fancy links to the browser based versions of Word, Excel, PowerPoint, OneNote and Sway.
The extension sits as an icon in the browser bar, click on it to create new documents online.
Or see a list of Recently Opened documents in OneDrive or OneDrive for Business.
Go here for the Chrome extension and to the Windows Store for the Edge add-in.
