How to Recover Lost Data - OneNote

Rupinder 0

I signed out of my OneNote because I was receiving a sync error on my OneNote app on my ipad. Although the notebook it was referring to had been synced in the past, it was no longer loading. I signed out of my account and signed back in but the notebook is nowhere to be found. I really need that notebook and cannot find it anywhere. Its not even online even though it was in the past. Please help! I don't know how else to contact Microsoft about this because that notebook is very important and was synced a couple of months prior

Hi Rupinder,

On iOS, OneNote relies heavily on cloud sync (OneDrive). As a result, if the sync process is interrupted, notebooks may temporarily disappear from the app even though there’s a strong chance they still exist in the cloud.

Please go through the following steps carefully to locate your notes:

1/ Verify the account in OneNote

Open OneNote
Tap your profile icon (top-left corner)
Confirm the email address currently signed in

If you’re signed in with a different account, your notebooks will not appear—even though your data is still stored elsewhere.

2/ Check your notebook from a browser

On your iPad (using Safari or another browser), please visit:

Then, sign in with your account.

Look for your notebook under your files or notebooks list

If you see your notebook, it means your data is safe.

3/ Reset the OneNote app (clear app state)

To ensure a clean sync:

Go to Settings > General > iPhone Storage
Select OneNote

You will see two options:

Offload App

Removes the app but keeps its data
May not fully fix sync issues

Delete App

Completely removes the app and all cached data

It is recommended to select Delete App to fully clear any corrupted cache.

Reinstall OneNote from the App Store
Sign back in using the correct account

4/ Check OneDrive Recycle Bin

If the notebook doesn’t appear, please go to OneDrive (via browser)

Open the Recycle Bin

Restore anything related to your notebook

For more information, please consult: Find OneNote notes, pages or tabs - Microsoft Support

5/ Contact Microsoft Support:

If you’re still unable to locate your notes after these steps, the most effective next step is reaching out to your IT admin and ask them to use their admin credentials to submit a support request through the Microsoft 365 Admin Center.

Microsoft also provides customer service phone numbers based on your region. Your IT admin can find the appropriate contact number here: Customer service phone numbers - Microsoft Support

This route ensures that a Microsoft support engineer can initiate a remote session to investigate backend configurations, run advanced diagnostic tools, and, if necessary, escalate the case to specialized teams with access to internal systems and logs. These backend resources are essential for resolving issues that go beyond what’s visible in the user interface.

As community moderators, we’re here to guide you, but due to privacy and security limitations, we don’t have access to the backend tools required for a full resolution. For this reason, contacting Microsoft Support via the Admin Center is the most secure and efficient way forward.

I hope this helps you resolve the issue quickly. I’m glad to assist and truly hope the information provided has been useful. Please feel free to reach out anytime if you need further assistance.
