Product

Device & OS
not provided
Scenario
Attempting to access important notes and sync documents for an exam after reinstalling the OneNote application.
Observed behavior
OneNote fails to synchronize notebooks and displays an error stating it cannot connect to the server.
Before you start

Ensure your tablet is connected to a stable Wi-Fi network and verify that you remember the exact Microsoft account credentials associated with your notebooks.

Solution 1Recommended

Verify Cloud Storage and Reconnect Account

Confirm your notebooks exist on the cloud to prevent data loss, then refresh your account connection within the app.

Reinstalling OneNote clears the local application cache. If the notebooks were not fully synced to OneDrive or SharePoint before the app was deleted, the local copies might be lost. You must verify their existence online first.

1
Check OneDrive or OneNote Web

Open a web browser on your tablet or a computer and log in to OneNote.com or OneDrive with your Microsoft account to verify your notebooks are safely stored in the cloud.

2
Sign Out of the App

Open the OneNote app on your tablet, navigate to the account settings menu, and manually sign out of your Microsoft account.

3
Sign Back In and Sync

Sign back into the OneNote app using the exact same account credentials verified in the first step, and wait for the application to pull the notebooks from the server.

Verify Cloud Storage and Reconnect Account
Data Loss Warning: Never delete the OneNote application to troubleshoot issues unless you have already confirmed that your recent notes are successfully synced to the cloud.

Log into OneNote.com or OneDrive.com using your Microsoft account via a standard web browser. If your notebooks appear there, they are safe and can be re-downloaded to your tablet once the app connection is fixed.
