A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
Hello Araceli Vasquez,
Based on the screenshot you uploaded, we noticed that you have two accounts, one is a school account and the other is a personal account.
Therefore, we need to confirm with you which account you have lost OneNote notes. If it is a school account, then you may need to contact the school administrator to see if your note content was deleted by the administrator, which may be the cause of the problem.
In addition, if the OneNote notes under your personal account are lost, and you can see from the screenshot that you stored the notes in OneDrive, you may need to contact the OneDrive team and ask them to help you retrieve the notes.
As said at the end of this article, if you’ve followed the steps in this article and still need help, email the OneDrive support team.
