Check Microsoft Service Status
Verify if the issue is caused by a widespread Microsoft server outage rather than a local configuration problem.
Sometimes connection timeouts are on Microsoft's end. Before changing your computer's settings, it is best to check if their servers are running normally.
Open your web browser and navigate to the official Microsoft 365 Service Status page.
Look through the list of services for any reported issues related to Microsoft OneNote, Office for the web, or OneDrive.
Temporarily Disable Firewall or Antivirus Software
Test if overly aggressive security software is blocking OneNote from connecting to Microsoft servers.

Frequently Asked Questions
Why does OneNote show as offline when I have plenty of OneDrive storage?
This happens when the application is blocked from communicating with Microsoft's servers. It is usually caused by a network restriction, strict firewall settings, antivirus software interference, or a temporary Microsoft server outage, rather than a lack of storage.
How can I manually force OneNote to sync my notebooks?
In the OneNote desktop application, you can force a sync by right-clicking the specific notebook's name in the sidebar and selecting 'Sync This Notebook Now', or by pressing the Shift + F9 keyboard shortcut.
Are the tech support phone numbers found in error pop-ups safe to call?
No. You should never call unverified support phone numbers found on random forums or error pop-ups. These are typically tech support scams designed to steal your information. Always use the official Microsoft support website.
