How to Fix OneNote Desktop Connection Issues with OneDrive and SharePoint

Product: Microsoft OneNote
Device & OS: not provided
Scenario: Attempting to open, sync, or save notebooks in OneNote Desktop connected to OneDrive or SharePoint.
Observed behavior: OneNote displays offline and permission errors such as 'We couldn't open that location', fails to synchronize, and cannot reliably open or save cloud notebooks.

Before you start

Verify that your internet connection is stable and ensure you can access your OneDrive or SharePoint account through a web browser before troubleshooting the desktop application.

Solution 1Recommended

Test with a New Notebook and Check Network Settings

Use this solution to determine if the syncing error is isolated to specific notebooks or caused by a system-wide network restriction like a firewall or VPN.

Network security tools or corrupted notebook files can prevent OneNote Desktop from reaching Microsoft's servers. Isolating the issue helps determine the exact cause.

Create a new notebook online

Open your web browser, navigate to OneNote for the Web, and create a brand new notebook.

Open in desktop app

Click the 'Open in Desktop App' button from the web browser to see if the new notebook successfully opens and syncs locally.

Disable network security temporarily

If the notebook fails to open, temporarily disable your VPN, firewall, or third-party antivirus software, then attempt to sync the notebook again.

Test with a New Notebook and Check Network Settings

Network Configurations: If disabling the VPN or firewall resolves the problem, you will need to whitelist OneNote and OneDrive traffic in your security software's settings.

Solution 2

Contact Microsoft Support via Microsoft 365 Admin Center

If all notebooks fail to open regardless of network settings, backend activity logs need to be reviewed by Microsoft Support.

Frequently Asked Questions

Why does OneNote say I don't have permission to open my own notebook?

This error often occurs due to cached login credentials conflicting within the desktop app, or restrictive network settings like VPNs blocking the authentication tokens required to connect to OneDrive or SharePoint.

Can I still access my notes if the OneNote desktop app won't sync?

Yes, your notes are safely stored in the cloud. You can log into OneNote for the web using any standard browser to view, edit, and manage your notebooks directly from OneDrive while you troubleshoot the desktop application.

How do I clear cached credentials for Microsoft Office apps?

To clear cached credentials on a Windows PC, sign out of all Microsoft accounts in your Office apps, close the apps, open the 'Credential Manager' from the Windows Start menu, navigate to 'Windows Credentials', and remove any saved credentials related to Microsoft Office. Then, restart your computer and sign back in.

Why do Word and Excel sync properly while OneNote fails to connect?

OneNote handles synchronization fundamentally differently than Word or Excel. Instead of saving an entire file at once, OneNote continuously synchronizes data in smaller chunks (sections and pages), making it much more sensitive to network interruptions, proxy settings, or server-side sync glitches.
