Frequently Asked Questions

Why does my Surface Slim Pen eraser work in Word but not in OneNote?

This usually indicates a synchronization bug or misconfigured setting specifically within the OneNote app. Because the hardware works in Word, the pen itself is fine. Updating the OneNote application and resetting Office settings typically resolves the software conflict.

Will resetting Microsoft 365 delete my existing OneNote notebooks?

No, your notebooks are safely synced and stored in your Microsoft OneDrive account. However, you should ensure that all recent offline changes are fully synced to the cloud before you perform a repair or reset.

Does it matter if I am using OneNote for Windows 10 or the OneNote desktop app?

Yes, they are different applications built on different frameworks. The OneNote desktop app (included with Microsoft 365) receives different updates than the OneNote for Windows 10 app. Make sure you are updating and repairing the correct version installed on your device.

How do I check if my pen button is correctly mapped in Windows?

You can verify your pen mappings by opening Windows Settings, navigating to 'Bluetooth & devices', and selecting 'Pen & Windows Ink'. Here you can customize what the top button and shortcuts do, though the physical eraser tip relies on app-level support.
