When you sync OneNote notebooks, you ensure your work on Microsoft's notes composition app is consistent and backed up across your devices.

OneNote automatically saves your work through its notebook syncing feature, but Windows PC users can disable and re-enable it at any time.

You can sync your ‌iPhone‌ or ‌iPad‌ to a Windows PC by physically connecting them, but did you know that you can sync your Apple device by having them connected over same Wi-Fi network?
