Hello, thank you for reaching out to Microsoft Q&A.
Could you please check if you're able to sign in with your account on https://onedrive.live.com/ using an incognito tab?
If your access is only blocked on OneDrive and you can access your account on other Microsoft services, such as Office or Outlook, you can email your concern to the OneDrive support team via email or try the account recovery form-
Before that, have you tried resetting your password and see if you can sign in?
If this is a personal account, please use the following link to reset the password: https://account.live.com/ResetPassword.aspx
If that did not help, email your problem to the OneDrive support team using the link here-

Alternatively, you can try the account recovery form below to unblock your account.
Important: The account recovery form can only be used if two-step verification isn't turned on.
Note - This is a peer-to-peer support forum. Account or billing-related queries fall outside the scope of our community guidelines, as they usually require sharing personal information. Posting such details in a public forum poses security risks and violates Microsoft’s terms and conditions. For this reason, we can only offer general guidance on how to recover your account.
Let me know if you still need more help.
