Hi Jay,
Thank you for using Microsoft products and making community posts.
I understands the importance of resolving this issue, Don’t worry I will be helping you with this following steps.
- Feature Removal – Microsoft announced that the ******@onenote.com email feature will be removed in March 2025. If you're trying to send emails to OneNote, you may need to use the Send to OneNote feature instead.
- Sign-in Loop Issue – Other users have reported the same issue where the URL keeps redirecting them to a sign-in page instead of the email settings. This could be a bug or a change in how the feature works.
- Alternative Solutions – Some users on Reddit have mentioned that the feature stopped working for them months ago, and Microsoft support suggested creating a new user profile, though this didn’t help
Please feel free to let me know how it goes.
