Managing personal Outlook.com account settings, security, and privacy
Hi,
Microsoft account recovery is a fully automated process.
In this situation, the only way to recover the account is by using the Microsoft account recovery form. For the link and instructions, please refer to Step 3 in the article below:
Help with the Microsoft account recovery form:
You can submit the recovery form up to twice within a 24-hour period. If your first attempt is unsuccessful, you can try again and provide any additional information you remember that may help verify your account ownership.
If the recovery form continues to fail, unfortunately, there is no alternative recovery method available, and the account may not be recoverable.
If you receive an “Account does not exist” error message, this usually means the hacker successfully changed the primary email address on your account. In this situation, the hacker may have taken over the account, and it is usually not recoverable. I’m sorry.
