‘Invalid NoteBook Error Name’ error in OneNote

After investigating this particular issue, it turns out that there are a couple of underlying causes for the ‘Invalid Notebook Name‘ error in OneNote. Here’s a shortlist of potential culprits:

  • Outdated OneNote version – As it turns out, an outdated OneNote version is often the underlying cause for this error message. Several affected users that were previously encountering the same problem have managed to fix the issue by forcing the app to update itself to the latest version.
  • Corrupted Office / OneNote installation – File corruption affecting the Office installation or the standalone OneNote app can also cause this error on a Windows 10 computer. If this scenario is applicable, you can fix the error by repairing the OneNote UWP app or repairing the entire Office installation if you are using the desktop version.

Now that you know every potential cause of this issue, here’s a list of methods that other affected users have successfully used to resolve the ‘Invalid Notebook Name‘ error in OneNote:

Method 1: Updating OneNote to the Latest Version

According to some users that we’re also seeing this error, this could be a symptom that you’re using an outdated version of OneNote. Keep in mind that by default, the app is configured to update itself, but there are some utilities that will actively block the auto-update function from kicking in.

If this scenario is applicable, you should be able to fix the issue by opening the OneNote app and forcing the app to update itself to the latest build available.

To make matters easier for you, we’ve put together a step by step guide that will walk you through this process:

  1. Open the OneNote app that is causing this error.
  2. Next, click on File from the ribbon menu at the top, then click on Account from the vertical menu on the left.
    Accessing the Account tab
  3. Once you’re inside the account menu, click on the drop-down menu associated with Office Updates, then click on Update Now from the list of available options.
    Updating the Office app to the latest version
  4. If a new version of the app is found, follow the on-screen prompts to complete the installation of the newer version.
  5. Restart your computer and see if the issue is fixed once the next startup is complete.

In case you still end up seeing the ‘Invalid Notebook Name‘ error when trying to create a new notebook, move down to the next method below.

Method 2: Repairing the OneNote Installation

In most documented cases, this particular issue is related to some kind of corruption that is affecting the local OneNote installation. At the time of writing this article, Microsoft has already released a couple of hotfixes for this issue, but new user reports are still popping up signaling that the issue is still not resolved.

If you already followed Method 1 and the issue is still not resolved, the next logical step you should take is to try and repair the installation.

However, the steps of doing this will be different depending on if you’re using the classic desktop version (part of the Office suite) or the newer standalone UWP version.
