OneDrive: Upcoming change to shared folder experience in Microsoft OneDrive
OneDrive will route shared folder links to a new People view organized by person rather than direct folder navigation. This changes how users access shared files from Teams, channels, email, and other sources but requires no admin action.
Microsoft's description
With this feature update, when a user clicks a link to a shared folder from Teams chat, channels, email, or other places, they will navigate to the shared folder within the People view of their own OneDrive. This new view, organized by people, will show and allow access to all the files and folders that have been shared with the user.
