Unable to login to OneNote on iOS using work credetials and authenticator

Hi Kubis,

Thank you for reaching out and for providing the detailed information and outlining the troubleshooting steps you have already completed.

Your IT department is correct. There is currently an ongoing Microsoft service incident affecting some users who access OneNote on iOS devices. The symptoms you described, including successful authentication followed by the message that the notebook has been deleted or moved, are consistent with this incident.

Your IT administrator can review the latest status, affected services, available workarounds, and Microsoft’s progress by opening the issue ID OP1454727 via Service health - Microsoft 365 admin center.

The engineering team is aware of this issue and is actively working toward a resolution. Based on the latest update, the recent change has already been broadly reverted across the Production environment. If the recovery continues as expected, you should be able to use OneNote normally again soon.

In the meantime, please continue using OneNote on the web, Windows, or Android, since those platforms appear to be working normally for you. Reinstalling the iOS application or repeating the authentication process is unlikely to resolve the issue while the incident remains active.

I hope you found the answer helpful, and I would greatly appreciate it if you could mark it as accepted. This helps highlight the solution for others who may be searching for similar information in the community. Your contribution not only supports fellow users in finding the right guidance more quickly, but also helps build a more resourceful and collaborative space for everyone. 

Thank you for your kindness and contributions to the forum. Wishing you a great day ahead.
