How to Fix OneNote Working Offline and Sync Problems on iPad
Question details
The user needs to resolve an issue where OneNote fails to synchronize notebooks and remains stuck in offline mode on an iPad.

- Product
- Microsoft OneNote
- Device & OS
- iPad
- Scenario
- Attempting to sync notebooks on an iPad after an app update, despite having an active internet connection.
- Observed behavior
- The application displays a 'Working Offline' status, stops synchronizing notes, and may occasionally show a black screen after reinstallation.
Manually back up any unsynchronized notes by copying and pasting the text into a local document or another app, as resetting the application will result in permanent data loss for un-synced edits.
Reset OneNote Settings and Clear Credentials
Resetting the application forces it to clear corrupted caches and login credentials, which resolves most offline synchronization bugs on iPadOS.
This method clears out the local cache and forces the application to re-download your notebooks from the cloud. Ensure you have backed up any offline changes before proceeding.
Navigate to your iPad's main Settings app, scroll down the left sidebar, and tap on 'OneNote' under the Apps section.
Tap on 'Reset OneNote'. On the next screen, toggle on both the 'Delete All Notebooks' and 'Delete Login Credentials' options.
Force close the OneNote app by swiping it away in the multitasking view. Reopen the app and sign in again with your Microsoft account.
After the notebooks reload, look for a section named 'Moved Sections' or 'Moved Notebooks'. This area may contain fragments of unsynchronized content recovered during the reset.

Update or Perform a Clean Reinstallation
If resetting the application does not work or results in a black screen, completely reinstalling the app ensures all corrupted installation files are removed.

Frequently Asked Questions
Why does my iPad say OneNote is working offline?
This typically happens when the application's local cache becomes corrupted after a software update, or when your login token expires, preventing the app from establishing a secure connection to OneDrive.
Will reinstalling OneNote delete my unsynced notes?
Yes, completely uninstalling the application from your iPad will permanently delete any notes or changes that have not yet been successfully synced to the cloud. You must manually copy and paste unsynced text to a different app before uninstalling.
What should I do if the app shows a black screen after resetting?
A persistent black screen indicates a severe application glitch. To resolve this, you need to completely uninstall the app from your iPad, restart the device, and then perform a fresh installation from the App Store.
Where can I find my lost notes after a reset?
After signing back in and allowing your notebooks to sync, check your notebook list for automatically generated folders named 'Moved Sections' or 'Moved Notebooks'. The system attempts to salvage unsynced offline edits and places them there.
