Hello,
Welcome to the Microsoft Outlook Community.
Good afternoon. I'm so sorry for what you're going through.
When a Microsoft account is compromised and security information such as nicknames, passwords, or verification methods are modified, the recovery process can become more complex. For security and privacy reasons, the Microsoft Community does not have access to accounts and cannot intervene in this process, which is performed exclusively by Microsoft systems. Please note that if the account has not been accessed in the last two years, it will be permanently terminated per Microsoft's account policy and cannot be reactivated, recovered, or used to create a new account with the same email address.
I recommend that you follow the guidelines in the official article to start recovering your account:
How to Recover a Hacked or Compromised Microsoft Account
If you can't regain access, you can also contact Microsoft Support by following these steps:
Contact Microsoft Support: https://support.microsoft.com/pt-br/home/contact
Type "Contact" into the search box.
Click Ask for help , and then select Contact Support or Sign in to contact Support.
Under Products & Services, select Account Security.
Under Category, select Technical Support, and then click Confirm.
If you do, select Chat with a support agent. If you prefer, you can also ask for help over the phone.
Chat support is available at specific times. If the option is not available at this time, please try again later or the next business day.
I hope these guidelines help resolve the issue. If you have any new questions related to Microsoft services, feel free to return to the Community. If possible, report the outcome. Your feedback can also help other users who are going through a similar situation.
