Obviously one of the keys to moving to O365 was the integrity of sharing and security. It was brought to my attention that users are able to see three (3) out of hundreds of OneNote notebooks that have not been shared with everyone. The way our notebooks are set up, the titles contain private information and is thus exposed to the organization. I know that the group or individual does not have permission to see the notebook because if they click on the card to open, they are redirected to the page saying they do not have access and can request permission. What suggestions (other than opening a ticket) can I do to troubleshoot why these notebooks are exposed.
