I can see in some discussion threads, that Azure tenant takeover is a thing,
and while the emails coming out may look half-legit, there should be a way
to determine they're spoofed.

Then the next step would be reporting a tenant issue perhaps. That's about
all I'm finding by looking at discussions with outbound.protection.outlook.com .
