Dear Xu, Sherry,
Good day to you! I hope you are doing well. Thanks for reaching out to our Microsoft Community Forum. We will be happy to help you.
I understand your concern—losing important documents can be very challenging. Based on your description, it seems you are unable to access your data in OneNote and are looking for ways to recover it. This situation may require advanced troubleshooting.
As a community forum, we have limited resources for in-depth troubleshooting. However, we have a dedicated support team equipped to handle such issues. I recommend contacting Microsoft technical support for assistance. They have the expertise and tools to help you recover your data. Here’s the support document with contact details: Get support - Microsoft 365 admin | Microsoft Learn. Additionally, if you are part of an organization, your Microsoft administrator can generate a support ticket through the admin portal. For convenience, here is the portal link: Microsoft 365 Admin Center. Lost data might be recovered from backend side with this Microsoft support channel.
I do apologize for any inconvenience.
Thank you in advance for your understanding. Your patience and cooperation are greatly appreciated.
Best Regards,
Nahid Sultan
