Frequently Asked Questions

Why does OneNote error E0001462 bukxq 30105 happen?

This error typically occurs due to a communication breakdown between the OneNote for Windows 10 desktop application and the OneDrive cloud servers. It is frequently triggered by corrupted local cache data, server-side outages, or network interruptions during the sync process.

Will I lose my notes if I close my OneNote notebook during a sync error?

Yes. If you close a notebook or sign out of the app before it has successfully synced to the cloud, any local changes or new notes that haven't been uploaded will be permanently deleted. Always manually copy unsynced content to a separate program like Notepad first.

How do I know exactly which OneNote pages failed to sync?

Log into OneNote Online using your web browser. The pages visible in the web version represent exactly what has been successfully saved to the cloud. Any pages that are missing or show outdated information in the web view are the ones failing to sync from your desktop.
