A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
Same problem, with everyone else:
As I was working on Onenote 2010 (V14.0.7237.5000) (win10 PRO), my content started vanishing. I ended up with blanc workbooks. Nothing else showed. Neither sections or pages.
I checked with my Ipad, Iphone, no problems there.
So I visited onenote.com. Everything looked fine.
I tried to "open in app" different pages (on the web). No way.
Check with my local IT if there is any blocked port, none.
HELP....
