I have used the Built-in app of OneNote almost everyday for well over a year. I meet with dozens of people a day and use it to take notes. I have always been able to click on a page, publish that page and then copy a link and send it to my clients for them to review. Today (March 21, 2018) I opened OneNote and was unable to Publish and copy the link. I was only given the option to Share the entire Notebook by providing an email address. I can't do this because then everyone will see everyone else's notes. This is also happening on my co-workers version. Has something changed? Is there a way to share only the page with an external person?
