A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
Dear Gerald Cayouette,
Thanks for visiting Microsoft Community. I am happy to help you.
I understand that you want to know how to manage personal and business accounts on the same application.
Are you unable to add accounts, or is it a matter of managing notes under different accounts?
I noticed that your thread was posted in the OneNote section. The OneNote application allows you to log in with different accounts.
When you open OneNote, click on the profile picture in the bottom-right corner, and select 'Connect services' to add different accounts.
I look forward to a more detailed description of your issue in your reply.
Best regards
