can’t logg in to my hotmail account

hello I have tried login to my email address for 2 weeks almost now I have important things in my mail as i need i change apple id then my hotmail was gone just so i have called sepport in Sweden but of course they can not help, i have linked apple id and as two factor authentication i think that's where all problems started when i try to log in so it says my mail is no longer but when i create a new one with the same address it says it's there
I get confused
