Microsoft 파일 호스팅 및 동기화 서비스입니다.
Hi JongJin,
I'm sorry to hear that your account was hacked. I can imagine how stressful it must be, especially when it involves a paid OneDrive subscription and important OneNote data.
Since you’ve already created a new Microsoft account and set up a new OneDrive plan, the next step is to cancel the old subscription and close the compromised account. If you still have access to the old account, you can go to account.microsoft.com/services, find your OneDrive subscription, and cancel it from there. If you can’t sign in, try using the account recovery form. If that doesn’t work, I recommend contacting Microsoft Support to request account closure and subscription cancellation due to unauthorized access.
Account Recovery Form: https://account.live.com/acsr
Contact Support: https://support.microsoft.com/en-us
Just to confirm, are you still able to access the old account on any device, or is it completely lost ? That will help me determine the best next step.
Let me know how it goes. I will be more than happy to assist you.
Regards,
Carlo
