Can a company legally send you a message asking you to resubscribe?
Isn't that the kind of email that anti spam laws are supposed to protect against given that I already unsubscribed?

When a correspondent disregards your wish to unsubscribe, it's only a violation of Can-Spam if that entity had no prior relationship with you. And even then a correspondent can claim not to have received your unsubscribe order.
The truth is Can-Spam offers almost no protection at all, in a practical sense. There are too many loopholes and gotchas.
The best thing you can do is what you're doing -- publicize your experience, hope that adverse publicity will change their behavior.
So, at he very least, that is impolite. I think the way to act is to send out a conformation message that includes an invitation to return: "you are now unsubscribed from all our email messages. If you want to change that in the future, do..."
But of course, you should only do that very shortly after the unsubscribe, not weeks later and certainly not months later (I don't know how much time elapsed in this case, so I might just be a poorly worded confirmation/reinvitation)
Obviously bad policy, but are you really going to attempt to sue Microsoft?
