A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
Hi Lisa Lukens,
As per the description, it seems like you have restored the folder successfully, but moving back into the folder in her OneDrive is not showing the content correctly in OneNote. If so, it is possible that the connection is broken in the backend of the class notebook, and I suggest you contact the school admin to raise a free support ticket from Microsoft 365 Admin Center.
The escalated support engineers there has more permission than us to offer the developed support like remote session, which may help to recover the folder connection with the class notebook and make it visible for the teacher and other students. This would be the most efficient way to handle this case for you and your students. Reference: Get support - Microsoft 365 admin | Microsoft Learn
How do I find my Microsoft 365 administrator? - Microsoft Support
Please correct me if I made any misunderstanding or if there have anything else I can do for you.
Your patience is highly appreciated. Hope you a nice day and stay safe!
Best Regards,
Mia
