Dosen't Microsoft rate limit the attempts? In that case ypu can just select a random number, the trie to brute force it until the code send is the one selected.
It doesn't seem all that limited; I'll get 4-5 in a burst, then nothing for a couple of hours or a day or so, then 4-5 more, and so on.
Been ongoing for a couple of months now, and given it's a random 6 digit number, I don't think they're even remotely doing enough attempts to try to brute force it.
If Microsoft accepts, let's say, 3 attempts per code send, they already tried 1200 numbers (per your 400 emails), it's still short to the 10**6 random attempts on average (supposing that the codes are entirely random). If you email is part of a list of a thousand, they already had tried more that a million and got access to some of them.
