Managing personal Outlook.com account settings, security, and privacy
I’m sorry to hear that you are facing this situation, Could you please share the exact error message displayed when you try to sign in? Please make sure to hide any personal information in the screenshot.
If the message says that the account has been locked, the first step is to submit Microsoft’s Account Reinstatement form:

However, if the message says that the account has been suspended, you will need to submit an appeal through the following page:

Unfortunately, regular support representatives cannot manually access the account, bypass its security protections, transfer the OneDrive files, or restore the account themselves. The account must be recovered or reinstated through the appropriate Microsoft review process.
