OneDrive for Business cloud storage and Office Online work best with the latest version of Microsoft Office, Office 2013, Office 2010, and Office 2011 and 2016 for Mac. With these versions of Office, you can select files stored in the cloud and edit them using your desktop applications instead of Office Online. Simply open the file you wish to edit, click ‘Edit in Word/Excel/PowerPoint’ and when you click ‘Save’ within those applications, you document will sync back to your storage.
