Gaurav0327 Random question on a random blog article, eh? 🙂 Not sure what issue you are referring this, but it has nothing to do with this change. If the question is how can a user authenticated in Outlook mobile to use the Send to OneNote feature. Then the answer is that Send to OneNote in Outlook mobile does not allow users to sign into the add-in. They must sign-in to the OneNote add-in using Outlook desktop, Outlook for Mac, or Outlook web app from a PC/Mac. This is a design choice to ensure that work or school account data cannot be exfiltrated to personal OneNote account via the add-in. Add-ins in Outlook mobile are not protected by the Intune App Protection Policy - they are considered unmanaged.
