Hi, My name is Max and I think my account has been hacked. The email address on my account was changed by someone else, and now when I try to log in, it says my account doesn't exist. Everything I have is stored on that account, and I'm really worried about losing access. I have backup codes and old emails that can prove I'm the owner of the account if needed. Please help me recover it as soon as possible. I can provide any additional information required to verify my identity. .

    Hey there, Max

    The email address on my account was changed by someone else, and now when I try to log in, it says my account doesn't exist.

    If your email address was changed and you now see “account doesn’t exist,” your Microsoft account has been compromised. When attackers gain access, they immediately replace your security information with their own. They usually:

    Turn on two-step verification, because they know the recovery form cannot override it.

    • Add a new alias to your account and remove yours, which causes the “account doesn’t exist” error.
    • Change mailbox settings and remove your personal information to make recovery harder.
    • Unfortunately, once this happens, recovery becomes very limited.

    Please help me recover it as soon as possible. I can provide any additional information required to verify my identity.

    Your first hurdle is finding the email address the attacker added.

    Check your alternate email inbox, you may have received a notification about a new alias being added. If you find it, please try the recovery form: https://go.microsoft.com/fwlink/?linkid=2288285

    The second hurdle you are going to face is the two-step verification.

    Important

    This is the biggest barrier. If two-step verification is enabled and you cannot access any of the verification methods, Microsoft support cannot reset the password or change account details. This is a strict security policy to protect account data. This is stated at the top of the article for the account recovery form here: https://support.microsoft.com/en-us/accounts-billing/manage/help-with-the-microsoft-account-recovery-form

    Hackers often enable two-step verification because it prevents Microsoft from restoring the account. If the recovery form cannot verify your identity, or if 2FA blocks the process, the account cannot be recovered and you will need to create a new Microsoft account.

    I know this isn’t the news you were hoping for, but I want to be honest and set the right expectations. If you do find the alias or have any other details, feel free to share them, I’m happy to guide you through the recovery form step-by-step.

    Hope this helps,
    Nathan

    Follow these steps immediately to try to recover the Microsoft account and secure it:

    1. Use the official hacked-account recovery helper
      Since the email/alias was changed and sign-in now says the account does not exist, start with Microsoft’s dedicated hacked-account flow. It will route to the correct self-help or recovery options and, where possible, offer contact with an agent:
      • Go to the sign-in helper: Start.
    2. Run through the hacked/compromised account guidance
      The official process for a hacked Microsoft account is documented here:
      • How to recover a hacked or compromised Microsoft account.
        Key parts of that guidance:
      • First, scan the PC with an up-to-date antivirus (or Windows Defender on Windows 10/11) before changing any passwords.
      • Then change or reset the Microsoft account password if sign-in is still possible.
      • After regaining access, review account settings such as connected accounts, forwarding, and automatic replies to remove any attacker changes.
    3. If sign-in fails / account “doesn’t exist”: use the account recovery form
      When the alias and security info have been changed, recovery is only possible through the automated account recovery process. Support cannot bypass this:
      • Use the “Recover your account” flow described in My username and password have stopped working: Recover your account from that article.
      • If prompted to use the dedicated recovery form (ACSR), fill it out with as much detail as possible. The article Help with the Microsoft account recovery form explains how to prepare:
        • Provide all old passwords that might have been used.
        • Use exact subject lines of emails sent from that account, and names of contacts.
        • Include correct domain (for example, @outlook.com vs @outlook.co.uk).
        • Use any information from old emails, services used (Outlook, Skype, Xbox, etc.), and any other details remembered.
      • Backup codes and old emails that prove ownership should be used as data points when answering the recovery questions.
    4. Understand the limitation if security info and alias were fully changed
      From Microsoft Q&A guidance in similar hacked-account cases:
      • Account recovery is an automated process; even Microsoft Support cannot manually restore access.
      • If the attacker has changed the primary alias and/or replaced all security info (email/phone/2FA), and the recovery form cannot verify ownership, the account is usually no longer recoverable.
      • If a recovery request is denied, submitting another request with more accurate and detailed information is the only available option. If repeated attempts fail, the account and its data (including OneDrive) cannot be restored.
    5. If a security info change is pending
      If at any point a “security info change is still pending” message appears when trying to manage security info, follow the built-in options on that page:
      • Use Let us know if the change was not made by the account owner to trigger the unauthorized-change flow.
      • If access to the old proofs still exists and the change was initiated by the owner, use Cancel this request.
    6. After (and if) access is restored
      Once access is regained:
      • Immediately remove any unknown aliases from “Manage how you sign in”.
      • Add additional secure verification methods (phone, alternate email, Microsoft Authenticator, etc.) as described in How to help keep your Microsoft account secure.
      • Review recent activity on the Security basics page and mark any sign-ins that were not performed by the owner so Microsoft can help secure the account.

    If the automated recovery form ultimately cannot verify ownership, there is no further escalation path documented; in that case, the account and its stored data cannot be recovered.
