Hi @Valerie Brown
Welcome to Microsoft Q&A Forum.
I know how discouraging it can be when a feature doesn’t behave the way it should, particularly when it impacts several teams at once.
I have tested this feature in my own environment, and it appears to be working normally, so I would like to suggest a few steps that may help resolve the issue on your side:
1.Check the team type:
Class Notebook is designed specifically for class teams, and it may not function properly with other types like "Staff" or "Other".
You can find more information about selecting the correct team type here:
Choose a team type to collaborate in Microsoft Teams - Microsoft Support
2.Try using Teams on the web:
Go to https://teams.microsoft.com, sign in, and access your class team there. Sometimes the web version works better for certain setup steps.
3.Create the notebook manually:
After creating it, copy the notebook link.
Then go to your team, select Add a tab > choose OneNote > paste the link > click Save.
Please note that after pasting the link, it may take a few moments for the notebook to fully load and appear in the tab. If it doesn’t show up immediately, give it a little time and try refreshing the tab if needed.
I hope this helps. If the issue continues, feel free to share more details and I’ll be happy to assist further.
