Onenote synch

Question

I have One note on My Win 010 desktop, Win 11 Tablet and Android phone. It seems that on my phone, it is not in sync with the other devices. What can I do about this? My concern is that if I simply force a sync with the phone that I will lose the more up to date info on the other devices.

To keep OneNote on Windows 10, Windows 11, and Android in sync without losing newer content, follow these steps, starting from the Android phone and then verifying on the other devices.

1. Verify internet and service health

• Make sure all devices (desktop, tablet, phone) have a reliable internet connection.
• If the notebook is on OneDrive, check the OneDrive Service Health page for outages. If OneDrive has issues, OneNote sync will be affected.

2. Check which version is actually up to date

• On the Windows device where the latest edits were made, open OneNote.
• Select File > Info > View Sync Status for the notebook.
• Confirm there are no sync errors and that this device has successfully synced. This ensures the “master” copy in the cloud is current before forcing sync on the phone.

3. Avoid sign-out/reinstall while troubleshooting

• When troubleshooting sync issues, do not sign out of OneNote or remove/reinstall the app on the Windows devices, as this can risk data loss if unsynced changes exist.

4. Reset credentials on Android (safe for content already in the cloud) On the Android phone:
5. Open OneNote.
6. Tap Notebooks (bottom left).
7. Tap the three-dots menu (⋮) in the upper-right corner and choose Settings.
8. Tap Account.
9. Tap Sign Out, then OK.
10. Use the recent apps button, find OneNote, and swipe it away to fully close it.
11. Start OneNote again and sign in with the same account used on the Windows devices.

This resets credentials and fixes many authentication-related sync issues without overwriting cloud content.

5. Force sync on Android after confirming cloud is current Once the Windows device has fully synced and the cloud copy is confirmed current:
6. On Android, open OneNote.
7. Find the notebook that is out of sync.
8. Tap the three-dots menu (⋮) in the upper-right corner.
9. Choose Sync (account name) notebook.
   • To sync all notebooks, go to the list of notebooks, tap the three-dots menu, and choose Sync all.
10. Leave the device on and connected until sync completes. For large notebooks or first-time syncs, this may take a while.

Because the Windows device synced first, the cloud version already contains the latest edits. The Android sync will pull those changes down rather than overwrite them.

6. If notes still don’t match

• Open the same notebook in a browser via https://www.onenote.com from a PC.
• Check whether the web version matches the Windows desktop version.
  • If the web version is missing changes, the issue is with the device that made those edits not fully syncing.
  • If the web version is correct but Android is not, repeat the Android force-sync steps and ensure OneNote stays in the foreground until sync finishes.

Following this order—sync Windows to cloud first, then Android—prevents loss of newer content from the desktop/tablet while bringing the phone up to date.

Answer 2

For me, just the sign out & back in on the Android version seems to have worked.
