    NO! This is not spam. I try to report spam to the spammer's host.
    Spam from Microsoft, however, requires that I know which Microsoft
    service is the origin (e.g., Azure, 360). Each service has a different reporting process.

    How can I tell which Microsoft service is the source of spam?

    When I complained to <junk@office365.microsoft.com>, they replied that
    this was from Azure and required a different way to complain.

    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 .
