Check Microsoft 365 Service Health and Force Sync
Rule out widespread Microsoft 365 server outages and manually trigger the synchronization process.
Often, sync error 0xE000002E is tied to temporary Microsoft 365 server-side incidents (such as OP420363). Checking the service health helps determine if the issue requires action on your end or if you simply need to wait for Microsoft to resolve a backend outage.
Log in to the Microsoft 365 admin center using your administrator credentials, navigate to 'Health', and click 'Service health' to check for any active advisories regarding OneNote.
If the service is healthy, open your OneNote desktop application, right-click the name of the affected Class Notebook in the notebook list, and select 'Sync This Notebook Now'.
Click 'File' > 'View Sync Status' or click the sync icon to confirm whether the 0xE000002E bukxo 30103 error has cleared.
Update the OneNote Client Application
Ensure your OneNote client is running the latest version, which may contain patches for known synchronization bugs.
Try WPS Office for Reliable Document Management
