Frequently Asked Questions
Why does the OneNote migration tool fail to create a backup?
This error typically occurs due to insufficient local storage space on your hard drive, restricted folder permissions in the designated backup directory, or if the notebook file is currently locked by a background process.
Are my OneNote files automatically saved to the cloud?
Yes, modern versions of OneNote are designed to automatically sync your notebooks to OneDrive by default, provided you are signed in with your Microsoft account and maintain an active internet connection.
How do I force sync a OneNote notebook before migrating?
In the OneNote desktop application, right-click the specific notebook name in the left sidebar and select 'Sync This Notebook Now', or press Shift+F9 to trigger a manual synchronization of the active notebook.
Can I manually back up OneNote files instead of using the migration tool?
Yes. If you are using OneNote for Windows 10 or the desktop version, you can navigate to File > Options > Save & Backup, and click 'Back Up All Notebooks Now' to create a manual local backup of your files.
