Managing personal Outlook.com account settings, security, and privacy
Dear Luke O'Flynn1
Thanks for your reply
For your situation, I can understand that you want to recover your account as soon as possible, I also know that the account contains your onedrive file, which is very important for you.
My suggestion is that you can make an account complaint, you can click on the link below to make an account complaint to try to see if you can recover your account, I hope you can recover your account, good luck.
