Office 365 photo visibilty to and from external organisations

Question

I am wondering if there is a possibility for a organization (in Office365) to be able to view external organizations senders profile pictures in Outlook? Or is federation between tenants a requirement? Today they can only se the initials.

Answer 1

No, because the pictures are in Azure. not in the email. The external user would need to add the picture to their own contact for that sender.
