Solution 1Recommended

Verify Web Access and Reinstall OneNote for Mac

Check if the notebook is accessible through the browser to isolate the issue to the Mac application, then perform a clean reinstall to fix corrupted local files.

Often, the 'cannot open this location' error is isolated to the local cache or installation of the desktop app. Confirming cloud accessibility ensures your data is safe before you proceed with a reinstallation.

1
Test Access on OneNote Web

Open a web browser, navigate to OneNote.com, and sign in with your Microsoft credentials. Attempt to open the problematic notebook. If it opens successfully, the issue lies with your local Mac app.

2
Uninstall Microsoft OneNote

Open Finder and navigate to the 'Applications' folder. Locate Microsoft OneNote, drag it to the Trash, and empty the Trash to remove the application from your Mac.

3
Clear Local Cache Files

In Finder, press 'Cmd + Shift + G' to open the 'Go to Folder' menu. Type '~/Library/Containers/' and press Enter. Locate the 'com.microsoft.onenote.mac' folder and move it to the Trash to clear corrupted cache files.

4
Reinstall and Sync

Download the latest version of OneNote from the Mac App Store or Microsoft's official website. Install the application, sign back into your account, and allow it to securely sync your notebooks from the cloud.

Frequently Asked Questions

Why does OneNote say it cannot open this location on my Mac?

This error generally occurs due to missing folder permissions in OneDrive, a corrupted local application cache on your Mac, or an interrupted synchronization process between your device and Microsoft's cloud servers.

Will uninstalling OneNote for Mac delete my saved notebooks?

No, notebooks that have successfully synced to OneDrive are stored securely in the cloud and will not be deleted. However, any unsynced changes that exist only locally on your Mac will be permanently lost when the application is uninstalled.

Can I fix the location error without entirely reinstalling OneNote?

Sometimes the error can be resolved without reinstalling by manually closing the affected notebook, signing out of your Microsoft account within the app, restarting your Mac, and then signing back in to force a fresh sync connection.
