how do I recover my account that was changed email by someone I did not know and now I cannot have any excess to it

Use the Microsoft Sign-in Helper first. It is the primary recovery path for a hacked Microsoft account and can either guide through self-help steps or offer the chance to talk to an agent.

Recommended order:

1. Run a full malware scan on the PC first
   • Open Virus and threat protection.
   • Select Scan options > Full scan > Scan now.
   • This is important before changing any password, so the attacker does not immediately capture the new one again.
2. Try the Sign-in Helper tool
   • Enter the Microsoft account email address or phone number that was used to sign in.
   • If the account issue is detected, the tool will tell what action to take next.
   • If no issue is detected, it will guide through additional self-help steps.
3. If the password no longer works, use account recovery
   • On the recovery flow, enter the email address, phone number, or Skype name used to sign in.
   • Double-check the email domain and spelling.
   • If the original email is not recognized, try any other alias or phone number previously added to the account.
   • Choose where to receive the security code, enter the code, and set a new password.
4. If the recovery form is needed, complete it carefully
   • Microsoft recommends trying the Sign-in Helper before the recovery form.
   • Recovery form results are sent to the working email address provided in the form, usually within 24 hours.
   • If verification fails, the form can be retried up to two times per day.
5. If security info was changed and a pending-change message appears
   • If the message says “Your security info change is still pending” or “You can't access this site right now”, the account security info was replaced and there is a 30-day wait before the changes take effect.
6. After access is restored
   • Change the password immediately.
   • Review account settings such as connected accounts, forwarding, and automatic replies, because these may have been changed after the compromise.

Important limits:

• Support agents are not allowed to send password reset links or directly change account details.
• If two-step verification was turned on and there is no access to any alternate verification method, Microsoft states that support cannot help recover the account.
• The Microsoft 365 Basic subscription receipt may be useful as proof of ownership when discussing the case with support, but account recovery still follows Microsoft’s verification process.
