I'm sorry you're going through this—it's definitely stressful when important notes become inaccessible. Based on what you described (“the location may not exist or you may not have permission to access it”), this is likely related to a syncing issue between OneNote, OneDrive, or device permissions.

Here are a few steps you can try to resolve the issue:

Check OneDrive Access

• Go to https://onedrive.live.com and sign in with the same Microsoft account you use for OneNote.

Navigate to the Documents or OneNote Notebooks folder.

See if your notebook is listed there and try opening it directly from OneDrive in the browser.

Check OneNote Online

Visit https://www.onenote.com and sign in.

See if your notebook opens in the browser. This helps determine if the problem is just on the desktop or iPhone app.

Reopen Notebook in OneNote Desktop

If you're using OneNote for Windows 10 or OneNote 2016:

Close the notebook: In OneNote, go to File > Info > Settings > Close This Notebook.

Reopen it from OneDrive: Go to File > Open > Open from OneDrive, then sign in and locate the notebook.

Check OneNote iPhone App

Since you said it still shows up on your iPhone:

Open the notebook on iPhone and check if it is fully synced: Tap the sync icon or go to Settings > Sync Now.

If it’s accessible, try sharing a link to the notebook with yourself or copying pages into a new notebook just in case.

Permissions / Account Check

Make sure:

You are signed in with the same Microsoft account across OneNote, OneDrive, and the desktop app.

The notebook wasn’t accidentally moved to a shared folder or deleted.

If it’s in a shared folder, confirm you still have permission to access it.

Additional Tip:

If you recently changed your Microsoft account password, sometimes OneNote loses sync and gives permission errors. Signing out and back in can help:

In OneNote, go to File > Account > Sign out.

Restart the app and sign back in.

Let me know if any of these steps help—or share a screenshot (without personal info), and I’ll do my best to walk you through it!

You're not alone in this—many people have faced similar sync issues, and usually, it can be resolved without data loss.

Take care!

Hello, welcome to the Microsoft Q&A forum.

This means your notebook file in OneNote is corrupted and cannot be opened.

You need to extract the notebook from OneDrive and then upload it back to OneNote.

These are my thoughts and suggestions, and I hope they are helpful.
