Solution 1Recommended

Reset OneNote Credentials and Clear App Container

Clearing old Microsoft Office identities and removing the local OneNote container forces the application to fetch your updated OneDrive storage quota.

Sometimes the local OneNote application caches your old storage limit. Resetting the app environment on your Mac will prompt it to verify the newly purchased storage.

1
Verify Storage Online

Visit onedrive.live.com/managestorage in your browser and sign in with your Microsoft account to confirm the additional storage has been successfully applied to your account.

2
Sign Out and Quit Office Apps

Quit all Microsoft Office applications (Word, Excel, etc.). Open OneNote, sign out of your account, and then completely quit the OneNote application.

3
Move OneNote Container

Open Finder, press Command+Shift+G, and type ~/Library/Containers. Locate the 'Microsoft OneNote' folder and drag it to your desktop.

4
Clear Keychain Access

Navigate to Applications > Utilities and open Keychain Access. Search for 'Microsoft Office' and delete the associated identity entries to remove cached credentials.

5
Restart and Sign In

Restart your Mac, reopen OneNote, and sign in with your Microsoft 365 account to allow the app to rebuild its cache and resume syncing.

Reset OneNote Credentials and Clear App Container
Risk of Data Loss: Removing the local container will permanently delete any unsynchronized changes in OneNote. Ensure you have backed up offline notes before proceeding.

Frequently Asked Questions

Why does OneNote say I have no storage when I just bought more?

It can take up to 24 hours for OneDrive storage upgrades to reflect across all servers. Additionally, your local OneNote app might be stuck using an outdated authentication token that still recognizes the old storage limit.

Will I lose my notes if I reset OneNote?

Any notes that have successfully synced to OneDrive are safe and will reappear when you sign back in. However, unsynchronized notes saved locally on your device will be permanently lost during a container reset unless you manually copy them elsewhere first.

How do I check which OneNote notebooks are failing to sync?

You can check the sync status by right-clicking the notebook name in the OneNote interface and selecting 'Notebook Sync Status'. This menu displays individual sync errors and shows exactly which sections or pages are failing.

Can I sync OneNote to a different cloud service to avoid OneDrive limits?

No, Microsoft OneNote relies on proprietary syncing protocols built exclusively for Microsoft OneDrive and SharePoint. It does not support native synchronization to third-party services like Google Drive or Dropbox.
