Hi @HÀO TRẦN,
Thank you for posting in Microsoft Q&A Forum.
Regarding to your description, could you please share a few more details by the following:
- You mentioned that the Class Notebook was created in Teams, could you please go back to the Team and try opening the Class Notebook tab to see if it loads correctly?
- In your second screenshot, there is a notebook named "STANDAR ENTRY Notebook". Is this the same notebook you created in Teams and are now unable to find?
- Have you tried checking across all versions of Teams and OneNote (e.g., web versions of both apps)?
- Was the notebook created recently or a while ago? If it was created just recently, it might take a little time to sync and appear in the list.
- When you created the notebook in Teams, did you choose to create a new notebook or link to an existing one? Also, could you confirm the location where it was saved and are you using the same account to access both Teams and the OneNote Class Notebook management tools?
Thank you for your time, I'm looking forward to your response.
