Managing personal Outlook.com account settings, security, and privacy
I’m sorry you’re still unable to recover the account after trying the available recovery methods several times.
Since the attacker appears to have changed the primary sign-in address and your original email address is no longer recognized, please use another Microsoft account that you can access to contact Microsoft Support:
- Open Contact Microsoft Support.
- Select Show expanded list of products.
- Choose Outlook > Get Home support.
- Enter Account Recovery, then select Get Help > Contact Support.
- Sign in with another Microsoft account if you cannot access the affected account.
- Under Ask our Support Assistant, enter Talk to a live chat agent.
- Select Other Products > Manage Account Security > Chat with a support agent via web browser, if available.
As the affected account is no longer recognized, this is the only available way to contact Microsoft Support directly about the account. When connected, explain that the account was taken over, the primary sign-in address was changed without your permission, and the original address now shows that the account does not exist.
Please note that this is a user-to-user support forum. Moderators, contributors including external Microsoft employees cannot directly intervene in Microsoft product features or access back-end systems. Our role is limited to providing technical guidance on reported issues, requests, or ideas only.
I hope the support agent can review your case and advise whether any additional verification option is available.
