Hi @Toby McDaid
Thank you for contacting Microsoft Q&A Support.
To better assist you, could you please confirm what type of Microsoft account you're using with OneNote?
- Is it a work or school account (e.g., part of Microsoft 365 for Business or Education)?
- Or is it a personal Microsoft account (e.g., Outlook.com, Hotmail.com)?
This will help ensure the solution fits your setup.
Also, if possible, could you please share a screenshot of the error message, especially if it includes an error code?
In the mean time, if you're using a work or school account, please try the following steps:
1. Check the Backup Folder Location
- Open OneNote for Windows 10.
- Go to File > Options > Save & Backup.
- Review the folder listed under “Backup Folder.”
- Make sure:
- The folder exists.
- You have write permissions.
- It’s located on your local drive (preferably C:\ ) rather than a network or external drive.
- You have write permissions.
- The folder exists.
2. Ensure Notebooks Are Fully Synced
- If your notebooks are stored on OneDrive or SharePoint, confirm they are fully synced.
- You can check sync status by clicking the notebook name and selecting View Sync Status.
- If syncing fails, refer to Fix issues when you can't sync OneNote.
3. Try Manual Backup
- Instead of using the “Switch Now” wizard, manually back up your notebooks:
- Open each notebook.
- Use File > Export to save a copy of the notebook or individual sections.
- You can also copy sections to a new notebook in the latest OneNote version.
- Use File > Export to save a copy of the notebook or individual sections.
- Open each notebook.
4. Update OneNote
- Open Microsoft Store and check for updates to OneNote.
- Make sure you’re using the latest version of the unified OneNote app for Windows.
5. Move Local Notebooks to the Cloud
- If your notebooks are stored locally, consider moving them to OneDrive for better sync and backup support.
- Follow this guide: Troubleshoot moving notebooks to the cloud.
