Is it possible to transfer my xbox account to another email address?

My xbox account is tied to my hotmail from when i was a kid. I dont use the email, its been caught in data breachs and someone from china is continusly trying to access it but stopped by 2fa and strong password. I dont want to lose my games but i want to delete the hotmail account. Id like to transfer my xbox account to my current email address which is proton or at the very least a new outlook/ hotmail email. Is this possible as im worried about losing my games and game progress.
