Has anyone experience issues with OneNote app on Microsoft Teams? Either the web based or application, OneNote cannot be accessed even if a new one was created. It outputs an error of: 'We can't access this notebook. You might not have permissions to view it, but your IT Admin show be able to help you.'

As group owners/members, shouldn't we be able to access OneNote? Previously, we were able to access our notes without a problem but something must've changed recently.

We've checked some other groups and they are experiencing the same thing as well. If we open OneNote application on the computer, it does show our Notebooks that are missing on Teams. Any ideas what is causing these issues?

Thanks, Chris. Am hoping for a quick solution for this as onenote connection seems to be the achilles heel of Teams at the moment. I too am getting this error on a team that was working with onenote and now isn't.

Outlook for mac update series updates all occurrences. Update for Mac and Outlook I just updated my Macbook with the new Sierra update and the previous version of Outlook is not supported by this update. When I re-download Outlook, it does not allow me to fully download the program.

'y ou might not have permission to view it, but your IT admin should be able to help you.' Ironically, I am able to succesfully creste the tab I have a another team that I am unable to add pages to: 'We failed to create the notebook. Your IT admin should be able to help you.' I have a third team where the onenote pages were not created in the Site assets Onenote and have not found a way to 'Connect' to the site assets notebook.

And I have other teams that were set up in the same way and are working fine. Last week, I changed the Sharepoint permissions for the notebook and added specific users as owners to the onenote. That didn't fix it then, but today it is working. I really can't explain what fixed it because the other changes I made, could have just taken time to propagate. Nevertheless, there is a pretty good work around. Navigate to the OneNote file on Sharepoint. Get a sharing link for internal users.

Then switch back to team. Create a new tab, but select Website. Add the link. This will give you direct access to the onenote website. Although, you may have to login to O365 again. Hi Chris, I work on the OneNote team, specifically on the Teams integration and am very sorry to hear about the error you and the others on this thread are encountering. Can you please help by sending the following information to help us investigate?

1. Is this error affecting every team member, or only a few/the site owner? Can you send a screenshot of the error including any sessionID/errorID/correlationID that might be included? Are you able to access the notebook through the web browser? Also, I'd love to learn more about how you and your team uses Teams together with OneNote (what scenarios are most important to you, what you'd like to be able to achieve with the integration) in order to keep improving the experience. Let me know if you're interesed in chatting more:).
