Every time I try to start Onenote (Modern) in windows 10 it says the above followed by saying we are unable to sign you in, please try again later. It never actually works.
Now normally I would just uninstall and reinstall the app but it seems as if this particular app has been locked into the build. You cannot remove it. That's fine if it works, but if it does not then how the heck do you get it working again? Mail and Calendar work fine so it is not an authentication fault overall, just something in onenote.
Any help or hint would be useful.
