How to Fix OneNote Freezing During Sync on iPad
Question details
The user needs to resolve an issue where the OneNote application freezes completely on an iPad during the synchronization process.

- Product
- Microsoft OneNote
- Device & OS
- iPadOS
- Scenario
- Opening OneNote on an iPad, particularly when reconnecting to the internet to sync large or complex notebooks created on another device.
- Observed behavior
- The application freezes as soon as the device goes online and attempts to sync. Creating a new notebook on the iPad directly may also result in a stuck "Please wait" message.
Ensure your iPad is connected to a stable Wi-Fi network and verify that your unsynced notes are backed up elsewhere (if possible) before closing any notebooks or restarting the app.
Update Software and Restart the iPad
The most effective first step is to ensure your app and device OS are fully updated, which clears temporary glitches causing the sync to hang.
Software updates often contain essential bug fixes for synchronization loops and memory management issues on iPadOS.
Open the App Store on your iPad, tap your profile icon at the top right, scroll down to check for available updates, and tap 'Update' next to Microsoft OneNote.
Navigate to Settings > General > Software Update. If an update is available for your iPad, download and install it.
Press and hold the power button and either volume button until the power-off slider appears. Drag the slider, wait 30 seconds, then press the power button again to turn the iPad back on.
Launch OneNote and leave it open for a few minutes to see if the sync process can now complete without freezing.

Reduce Notebook Size on a Desktop Computer
Notebooks exceeding 2 GB or containing heavy attachments from a PC or Mac can cause the iPad app to freeze under the processing load.
Create a Smaller, Dedicated Notebook
If cleaning an existing large notebook is not feasible, migrating essential notes to a fresh, lightweight notebook can bypass the freezing issue.
Try WPS Office for Lightweight, Reliable Mobile Productivity
If you continuously encounter freezing issues when managing heavy Microsoft Office files on your iPad, consider switching to WPS Office. It provides a lightweight, highly compatible alternative for viewing, editing, and syncing your important documents across all devices without the heavy resource drain.
- 1. Download from the App Store: Open the App Store on your iPad, search for 'WPS Office', and download the free application.
- 2. Sign In for Cloud Sync: Launch the app and create a free account to enable seamless synchronization across your mobile and desktop devices.
- 3. Import Your Documents: Easily link your preferred cloud storage (like Google Drive or Dropbox) to access and manage your files without sync freezing issues.

Frequently Asked Questions
Why does OneNote freeze on my iPad exactly when I connect to Wi-Fi?
When your iPad connects to the internet, OneNote immediately initiates a background sync. If it encounters a massive notebook (especially those over 2 GB) or highly complex formatting originally created on a PC, the iPad's memory is overwhelmed trying to process the data, causing an immediate freeze.
Will reinstalling the OneNote app fix the freezing issue?
Reinstalling the app can clear a corrupted local cache, which sometimes resolves sync hangs. However, if the root cause is a notebook that is simply too large, the issue will return as soon as it tries to redownload it. Be warned: deleting the app will erase any local notes on the iPad that haven't synced to the cloud yet.
How can I check the file size of my OneNote notebook?
You cannot check the file size directly within the iPad or mobile app. To check the size, log into your OneDrive account on a web browser, navigate to your 'Documents' folder (or wherever your notebooks are stored), and look at the file size listed in the details column.
Can I force a specific notebook to stop syncing on my iPad?
Yes. If the app freezes immediately, turn on Airplane Mode first. Then open OneNote, tap and hold the name of the problematic notebook in your list, and choose 'Close Notebook'. This removes it from your local device and prevents it from attempting to sync when you turn Wi-Fi back on.
