How to get the Onedrive add-in for Outlook

Hi, I've seen some computers have in Outlook Ribbon, "Save to Cloud" and also if you right click on mail attachment you get "Upload to Cloud", I have onedrive & onedrive for business installed on my machine but not seeing the "Save to Cloud" under Attachments ribbon, nor any other indications...

if I go to File --> Office Account --> I see my onedrive account connected... 

btw It's Outlook 2016

thank you for any help!
