Linking OneNote Class Notebooks to Teams for collaborative note-taking and organization
Hi Iseult,
Thanks for the clarification, it seems that you cannot open the class notebook in your team, and this also caused an error when you trying to create an assignment and add notebook resource.
Given that only you have the problem, you can ask the team owner to remove you from the team and then add you again to see if you can open the class notebook.
If that still cannot solve the problem, you may need to contact your school IT admin to report the problem for further assistance, admins can raise a ticket escalate the issue if necessary: Ways to contact support for business products - Admin Help
Sorry for the inconvenience to your work, I hope the above information can help you a little, please keep me informed of any concerns.
Best Regards,
Arck
