A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
Hi, Krris Vellayappan
Thank you for using Microsoft products and posting them in the community.
You can try the program in this article below first:
Find my lost notes - Microsoft Support
Then you can search for the missing content in OneDrive, refer to the article below:
Find lost or missing files in OneDrive - Microsoft Support
If none of that works, I'd recommend contacting OneDrive's support team and asking them to help you find it, but if that doesn't work either, then your files are probably indeed lost and there's very little hope of getting them back:
Here is the link to send an email to the OneDrive support team:
https://go.microsoft.com/fwlink/p/?LinkId=528676
Need to make sure you visit onedrive.live.com using your browser - click on the link - and it will automatically bounce back to your OneDrive web side and allow you to send the email.
I hope the above information can help you. Feel free to send a message if you need further help.
Best wishes
