How to Sync and Backup OneNote 2016 with OneDrive and Android
Question details
The user needs to configure OneNote 2016 notebooks to sync properly with OneDrive and an Android device while managing duplicate backup folders.

- Product
- OneNote 2016, OneDrive
- Device & OS
- Windows PC, Android
- Scenario
- The user has multiple OneNote notebooks and backup folders scattered across local storage and OneDrive, causing synchronization confusion across their devices.
- Observed behavior
- Unclear synchronization paths and disorganized backup folders make it difficult to determine which notebooks are actively syncing between OneNote 2016 and the Android app.
Ensure you have the login credentials for your primary Microsoft account ready, and do not delete or uninstall any existing notebook folders until you have verified your data is safely synchronized.
Consolidate and Sync Notebooks via OneDrive
Designate a single primary location in OneDrive to ensure seamless synchronization between your desktop and Android phone.
To resolve synchronization confusion, you must ensure that all devices are referencing the exact same cloud location rather than local copies.
Open OneNote 2016 on your PC. Click on 'File' > 'Info' and verify that your active notebooks are saved directly to your OneDrive account URL, not your local hard drive.
Install or open the OneNote app on your Android phone. Sign in using the exact same Microsoft account associated with your OneDrive. Wait a few moments for the cloud notebooks to appear and synchronize.
Create a test note on your PC and check if it appears on your Android device, and vice versa. This confirms the sync connection is actively working.
To maintain a safe offline copy, periodically download your notebooks from the OneDrive web interface or use the OneDrive desktop app to keep a local, read-only backup.
Only after you have confirmed that your notebooks are actively syncing and safely backed up, navigate to the old, confusing backup folders on your local drive and delete them to prevent future confusion.
Organize Your Documents Effortlessly with WPS Office
If managing complex Microsoft Office sync settings and duplicate backup folders is slowing you down, try WPS Office. It offers a clean, unified platform with built-in WPS Cloud, making it incredibly easy to back up, sync, and access your documents across Windows, Mac, iOS, and Android without the folder confusion.

Frequently Asked Questions
Why are there multiple OneNote backup folders on my PC?
By default, OneNote 2016 automatically creates periodic local backups of your notebooks on your hard drive. If you are also syncing these notebooks to OneDrive, it can appear as though you have duplicate files, causing confusion.
Can I safely delete old OneNote backup folders?
Yes, but you should only delete them after you have thoroughly verified that your primary notebooks are successfully syncing to OneDrive and are fully accessible on your Android device.
How do I force OneNote 2016 to sync immediately?
You can right-click the specific notebook name in the OneNote 2016 interface and select 'Sync This Notebook Now', or press Shift+F9 on your keyboard to force a manual synchronization of the active notebook.
Will reinstalling the Android app delete my notebooks?
As long as your notebooks are safely stored and synced in OneDrive, reinstalling the Android app will not delete your data. Your notes will reappear as soon as you reinstall the app and sign back in with your Microsoft account.
