All they would have to do is update the app and teams site to disable the upload pic option and have a change pic link that goes to the user profile page that honors the policy in outlook/SharePoint. You do not need to give the users the option to change their pic every single place imaginable. This is an eco system of apps. Send users to a source of truth for making changes that is governable. This could be fixed in a day. Not in over two years. COME ON MS!!!!!
I’m excited to announce that this feature is in internal testing, and should be coming soon! Thanks!~ Alex
