Accessing OneNote files with guest contributor

To add to your OneNote notebooks as a guest contributor, you need to ensure that you have the appropriate permissions granted by the owner of the notebook. Here are the steps you can follow:

1. Access the Shared Link: Open the shared link you received in your email or from the previous account. This should direct you to the OneNote notebook.
2. Sign In: If prompted, sign in using the account that was invited as a guest contributor. If you do not have an account, you may need to create one.
3. Edit Permissions: If you are unable to edit the notebook, contact the owner of the notebook to ensure that you have been granted editing permissions. The owner can adjust your permissions in the sharing settings of OneNote.
4. Collaborate: Once you have the necessary permissions, you should be able to add notes, sections, or pages to the notebook as needed.

If you continue to experience issues, it may be helpful to check the external collaboration settings in Microsoft 365 to ensure that guest access is enabled for the notebook in question.
