Forgive if its already been discused but is googel already aware of

Is envelope sender user@.onmicrosoft.com normal in non-spam
mail? Is it how all microsoft mail comes through? Or is it usually spam

Microsoft doesn't limit FROM header spoof? I saw message like:
Envelope from: example.user207@.onmicrosoft.com

For example if TO=rob...@example.com then FROM=supp...@robert.com
Is too complicated for microsoft check the FROM header belong to the
senders account?
