How to Fix OneNote Saved Offline Cloud Storage Full Error
Question details
The user is unable to sync OneNote notebooks due to a persistent out-of-storage error, even after purchasing additional OneDrive space.

- Product
- Microsoft OneNote
- Device & OS
- Mac
- Scenario
- Attempting to synchronize updated notebooks to the cloud after upgrading the Microsoft OneDrive storage quota.
- Observed behavior
- OneNote displays a 'Saved offline (out of cloud storage)' message and fails to sync locally saved changes to the cloud.
Before attempting any reset procedures, manually copy and paste any unsynchronized notes into a separate text editor or document app to prevent permanent data loss.
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.
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.
Quit all Microsoft Office applications (Word, Excel, etc.). Open OneNote, sign out of your account, and then completely quit the OneNote application.
Open Finder, press Command+Shift+G, and type ~/Library/Containers. Locate the 'Microsoft OneNote' folder and drag it to your desktop.
Navigate to Applications > Utilities and open Keychain Access. Search for 'Microsoft Office' and delete the associated identity entries to remove cached credentials.
Restart your Mac, reopen OneNote, and sign in with your Microsoft 365 account to allow the app to rebuild its cache and resume syncing.

Run the Office License Removal Tool
Use Microsoft's official license removal tool to completely wipe existing activation states if basic credential resetting fails to fix the sync loop.

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 Additionally, your local OneNote app might be stuck using an outdated authentication token that still recognizes the old storage limit.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.
