Access code troubles

FaZeTurbo

So my friend and I got this game, and mine worked perfectly, but his not so much. He had problems with his access code. He doesn't get the code in his email. He uses outlook, and he has looked everywhere in his inbox but it's not there. He was able to play last night when he randomly tried to sign in, and it didn't prompt him for a code. Support in not helpful, and he wants to play.
