Additional Class Notebook-related features and issues within Microsoft Teams for Education
Hi Nicole,
Actually, setting image as background is not directly applied to the class notebook, but only in the OneNote desktop app.
Within OneNote 2016 or OneNote for Windows 10, after inserting a picture, you can click the “set picture as background” button by right-clicking the picture to set it as background.
OneNote 2016:
OneNote for Windows 10:
And you can also set this setting in other notebooks in addition to class notebooks.
Best regards,
Madoc
