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 view the raw source, I see

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 .
