how to recover my data of microsoft onenote ?

Hello @Vivek Agarwal

One thing you can try first is checking whether your notebook still exists in OneDrive. Since OneNote on Mac stores its data primarily in the cloud, the notes may not be lost, they might just not be showing correctly in the app.

• Go to OneDrive in your browser and sign in with the same account you use for OneNote
• Look for your notebook in your files
• If you find it, try opening it again in OneNote

Alternatively, you can also simply sign in to OneNote on the web https://onenote.cloud.microsoft/ to quickly check whether your notebooks are still there.

If the notebook is visible there, your data is still safe, you may just need to reopen or resync it in the app.

However, may I know what type of account you are using to sign in to OneNote for better assistance? Is it a personal account (such as Hotmail/Outlook) or a work or school account?

Please try the suggestion above and feel free to share the result so I can continue assisting you.
