Frequently Asked Questions

Can I move the OneNote local cache to an SD card using junction points?

While it is technically possible using junction points in Windows, it is highly discouraged. Removable drives can cause the synchronization cache to become unreliable, which may result in sync errors or data loss.

Why can't I change the notebook save location in OneNote for Windows 10?

OneNote for Windows 10 is designed as a cloud-first application that stores notebooks exclusively on OneDrive. To save notebooks locally or to an external drive, you must use the OneNote desktop version included with Microsoft Office.

Can I move the entire Microsoft Office installation to my external drive?

No, Microsoft Office installation files cannot normally be moved to another drive without causing registry and functional errors. However, you can save individual documents and OneNote notebooks to external storage.
