Please note that this is zh-hk Q&A Forum, any threads should be posted in zh-hk. However, I will still provide an answer in English based on your initial response.
Hi @吳 宗育
I’m very sorry this happened. Since the attacker appears to have replaced the account aliases and security methods, your previous email address may no longer identify the account. This explains why both sign-in and the recovery form report that the account does not exist.
Please try the Microsoft Sign-in Helper using your original email address or phone number. Microsoft specifically recommends this tool for compromised accounts, and it may provide the appropriate recovery route or an option to contact an agent.
If the address is still not recognized, use Contact Microsoft Support and explain clearly that:
- The account was compromised through phishing.
- The primary alias and all sign-in methods were changed.
- Your original username now returns “This account doesn’t exist.”
- The recovery form cannot locate the account.
Please understand that forum moderators cannot access accounts or verify ownership. Microsoft support agents are also not permitted to manually change account details or send password-reset links, but they can guide you through the available official process.
Meanwhile, scan the affected device for malware and immediately change any passwords reused on other accounts.
Thank you for your understanding and time
