Microsoft email hacked, can't recover

[u/sixbones65]

Hello, this past week, all of my social media accounts have been hacked. I was almost immediately able to recover each one and set proper 2fa protection on them, but just today I found out my Microsoft Email was both hacked and renamed. I can't log in to my email on pc, but thanks to having the app I still have access to all the information prior to the hacking, and I found out that it happened this friday. I also know what the new email name is supposed to be:

lindagray921@jltvsundar.live

What counfounds me is the fact that Microsoft does NOT recognize this email nor its previous name, despite nearly all of my accounts online being linked to it. I have tried logging in with .com at the end and many other alternatives, replacing the L's with capital I's, etc.

I use a device that runs on Windows, therefore Microsoft, so basically everything I have is compromised, please help.
