Hacker destroyed my emails

Last July as I was boarding a plane and had no access to Wifi for 5 hours (worst nightmare ever), I realized someone hacked into my hotmail account. I had more than 20 years worth of emails there which is why I can't stray anywhere else. ANYWAY, the hacker wrote an email demanding money, and proceeded to lock me out of all of my apps and subscriptions... I couldn't do anything. He had forwarded everything to a different email and set up some rule. I finally was able to get back into my account on Microsoft but now I'm realizing I'm missing thousands of emails. I checked the rules, did all the troubleshooting steps etc. and anything prior to July 1, 2025 is just GONE. Can anyone help me recover these? I feel like they have to be on a server somewhere!
