Additional team and channel-related features and issues within Microsoft Teams for business
Hi Hilary,
I'm Ahmed and I am here & happy to help.
I apologize for the issue you are experiencing. Please be assured that I will do my best to provide a satisfactory response and assist you with resolving the problem.
This OneNote is under the same Teams account, right? You can also access this OneNote on the web https://www.onenote.com/, right?
Are you the OneNote owner? How many users are affected also with this? Does it link on Teams web App https://teams.microsoft.com?
Please share with me any error message -Please exclude any personal details-.
I hope this helps! Let me know if you have any further questions or concerns.
Best regards,
