OneDrive context menu (share, history, Free Space, Always keep) is missing

ReneZimmermann Nothing I found on the Internet worked for me. Instead of going thru support who apparently misunderstood the question in the first place (I am just assuming because the response and questions I received indicated that...) ... I decided to delete the user account (then a quick boot) and to re-add the user.  That worked right away, the OneDrive context menu section was there again.

Re-adding the user seems a little more work but in the end it was a quick solution compared to the time I had spent researching on the Internet and what would have been ahead of me with trial and error other recommendations.

Best of luck!
