If your account has been hacked and the email address has been changed, it's important to take immediate action to regain access. Here are some steps you can follow:
- Contact Support: Since you no longer have access to the account, you should contact Microsoft support directly. If you are part of a company or organization, reach out to your IT department for assistance. If you are an individual user, you can find support through the Microsoft 365 admin support page.
- Identity Verification: Be prepared to verify your identity. Microsoft may require information to confirm that you are the rightful owner of the account.
- Reset Password: If you can verify your identity, you may be able to reset your password. This could help you regain access to your account if the email address associated with it can be restored.
- Check for Compromised Accounts: If you suspect that other accounts may have been compromised, check their security settings and change passwords as necessary.
- Enable Two-Step Verification: Once you regain access, consider enabling two-step verification for added security to prevent future unauthorized access.
Following these steps can help you address the situation effectively.
