my acount got hacked and the login infomations got changed

Microsoft support cannot change the hacked account’s email address or password on behalf of the account owner.

Use this recovery path:

1. Start with the Sign-in Helper tool. It checks the account email address or phone number and either gives self-help steps or offers the chance to talk to an agent.
2. If the old sign-in name is no longer recognized, try Recover your account and enter:
   • the email address, phone number, or Skype name previously used to sign in
   • any other alias or phone number that was on the account, if the original email is not recognized
3. When prompted, choose where to receive the security code, enter the code, and set a new password.
4. If the account was hacked, first run a full antivirus scan on the PC before changing the password.
5. If recovery fails, submit the Microsoft account recovery form. The result is sent to the working email address provided in the form within 24 hours. The form can be retried up to two times per day.
6. If the username still is not found, use the contact support option and report that the username has stopped working.

Important limits:

• Support agents are not allowed to send password reset links or access and change account details.
• If the account is an Outlook.com account and it was temporarily blocked because of unusual sign-in activity, unblocking requires a password reset.
• If the account had aliases, any previous alias or phone number on the account may still help identify it.

After access is restored, review connected accounts, forwarding, and automatic replies, because those settings may have been changed during the compromise.
