I have got into a mess in that I clicked onto, "Insert" waited for the synct to do whatever it is supposed to then clicked onto "Picture" and the following came up in a box which I copied using Snipping Tool but it would not post the result here.

The words in the box were:
Location mot available.
C:|UsersB????\OneDrive\OneNote is unavailable. If the location is not on this PC, make sure that the deviec or drive is connected or the disc is inserted, then try again." etc etc

Is it possible to Uninstall and then reinstall OneNote?
