How do you permanently turn off new outlook?

I don't like it, I don't want it, I am not going to switch to it, and I never want to see it again. For the longest time it would periodically switch to the new outlook, I would turn it off, and submit feedback stating the previous. Now it auto opens every single time. I do not ever want to see the new outlook again for the rest of my life. Do not make me switch to Mac or Linux or whatever because I am petty and will eventually become so disgruntled and delete everything Microsoft and never spend another dime on anything they make over something stupid. I want to know a way to permanently delete the new outlook off my system so it doesn't get to that point.
