Frequently Asked Questions

Why is my OneNote showing an offline message on my new phone?

This usually happens because you haven't signed into your Microsoft account on the new device, or the app hasn't completed the initial synchronization of your notebooks from the cloud.

Can I sync my OneNote notebooks over cellular data?

Yes, but you may need to check your phone's and OneNote's settings to ensure the app has permission to sync using cellular data, as it often defaults to Wi-Fi only to save your mobile bandwidth.

What should I do if my notebooks are missing after signing in?

First, ensure you are signed into the exact Microsoft account used to create the original notebooks. Then, navigate to the Notebooks section, tap Settings, and manually trigger 'Sync all' to force the download.

Do I need to keep the app open to sync all my notebooks initially?

For a new phone with a large number of notes, it is highly recommended to keep the OneNote app open and your screen active until the first full synchronization is complete.
