Hi @Hyun Jang
Thank you for posting your question in the Microsoft Q&A forum.

I'm really sorry to hear about your account being hacked. It sounds like a frustrating situation. Unfortunately, it is impossible to suspend or temporarily deactivate a Microsoft account, but you can delete it if needed by following the instructions in this link: How to close your Microsoft account - Microsoft Support
Note that you'll need to sign in your account to request deleting it but as a Q&A forum, we can't provide direct support for account recovery or suspension here, but I can guide you on what to do next. You should contact Microsoft Support directly for assistance. They can help you recover your account or take necessary actions. You can reach them at Contact - Microsoft Support.
I hope this helps, and I wish you the best in resolving this issue quickly! Please get back to us if you need any further assistance.
