When you type a web address in your notes, OneNote automatically formats it as a clickable link. You can also add links manually and you can update them anytime.
Right-click the link you want to change and then click Edit Link.
Type the new URL or web address in the Address box, and click OK.
Note: If you don’t want a link in your notes anymore, you can remove it. Right-click the link and click Remove Link. You won’t see this option for a link created automatically by OneNote. To remove this kind of link, delete the web address.
