alt Hacker NewsWho even can be sure microsoftonline.com is legit. Microsoft's domain story is such a mess, I wouldn't be surprised if not even internally they have one complete list of all the domain assets they own.
But they are not alone. It is kind of ironic when companies insist that we check the domain to spot spam but are unable publish a list with all domains they officially use to send mail.

Tangent: I used to receive at least a dozen bank scam calls per day in India, especially during insurance renewal. I wanted the banks to publish official phone numbers and mandate their employees to use only official numbers.
Recently the regulatory bodies did just that and so the banks should only use 1600 numbers to contact their customers. My bank scam calls have dropped to 0.
Such a list will never exist in an organisation of this size, with the amount of delegated management and operations required for these functions. In fact, it’s unlikely such a list is even _allowed_ to exist given the sensitive nature of some areas of the business, being a publicly traded company which works directly with regulated entities and governments.
It’d be interesting to hear a senior old-timer from MS to weigh in on their blog about this, and similar/adjacent problems that arise from working across such a colossal entity.
It’s a wonder they ever release anything new, if I’m being completely honest. The amount of governance, hoops, process and procedure across every aspect of their business must be staggering.

That's because people report them as spam, so they hop domains to avoid that.
Bluesky is even worse, some of their emails come from "[email protected]".
They have to make posts to assure people it's not a scam, especially as they'll ask you to mail ID etc to that address:
