OneNote sync fails - 'Saved offline'

Hi John,

Thank you for sharing the details of your situation. 

The “Saved offline” status and error E0001475 indicate that OneNote is keeping the affected notes locally on your Mac but is currently unable to sync them to your organization’s OneDrive or SharePoint. Since your main notebook is syncing normally, the issue may be specific to the newly created notebook or its connection to the online storage location. 

Here are some steps you can try: 

1. Go to OneNote for the web and sign in with the same corporate account. 
2. Check whether the affected notebook appears and can be opened and edited online. 
3. In OneNote for Mac, update the application to the latest version, then restart the Mac. 
4. Open the notebook list, right-click or Control-click the affected notebook, select Sync, and then choose Sync This Notebook or Sync All Notebooks, if available.
5. If the notebook works correctly online, close and reopen the notebook in the OneNote desktop application. 
6. Try connecting the Mac to a different network, such as a mobile hotspot, then check whether the notebook syncs successfully. 
7. If the issue affects only this notebook, create a new notebook in OneNote for the web and copy a test page or section to the new notebook to see whether it syncs correctly. 

Before signing out, closing the affected notebook, or reinstalling OneNote, please copy any important unsynced notes to a safe location, as they may currently exist only in the local cache. 

If the issue persists, especially if the notebook cannot be opened or edited in OneNote for the web or multiple notebooks are affected, please contact your organization’s IT administrator. They can check your OneDrive or SharePoint access, available storage, Microsoft 365 license and organizational policies for any issues affecting OneNote synchronization. 

Additionally, if needed, your IT team can also raise a support ticket with Microsoft Support through the Microsoft 365 Admin Center for deeper investigation. They have access to backend configurations and can perform a more in-depth investigation. At the very least, they can provide the most effective workaround to ensure your experience remains smooth and secure.
