    Hi @David Ward 

    Thank you for posting your question in the Microsoft Q&A forum. 

    If someone has added a 1 TB file to your OneDrive and is actively deleting files from your device, you must take action immediately.  

    -Go to https://mysignins.microsoft.com/security-info and change your password right away 

    -Enable Microsoft Authenticator or SMS verification for two-factor authentication. This prevents unauthorized access even if someone has your password. 

    -Sign out everywhere to disconnect any unauthorized sessions from your account. 

    Since the channel tag is OneDrive for Business, the official Microsoft Support path is: 

    -If you are the admin, you can submit a support ticket via the Microsoft 365 Admin Center. 

    For further instructions, you can follow this guide: Get support - Microsoft 365 admin | Microsoft Learn.   

    -If you are not the admin, ask your organization's IT admin to open a Microsoft ticket immediately. 

    If you are using a personal Microsoft account: 

    Go to Microsoft Contact Us > Type "Support" and click Get Help > Click Sign in to contact Support at the bottom of the page. > Under products and Services, select Microsoft 365 and Office Option > Under category, select Technical Support > Chat with a support agent in your web browser.  

    I hope this helps.

    If someone has placed a large file in your Microsoft 365 account that you cannot remove, it is likely due to permissions set by the file's owner. In Microsoft 365, only the person who uploaded the file (the generator) typically has the ability to delete it unless they have shared those permissions with you.

    To resolve this issue, you can try the following steps:

    1. Contact the File Owner: Reach out to the person who uploaded the file and request that they delete it or grant you the necessary permissions to remove it.
    2. Check Shared Permissions: If you have access to the shared location where the file is stored, check if you can see the permissions settings to understand your access level.
    3. Use Microsoft Support: If the file is causing significant issues, consider contacting Microsoft Support for assistance with your account and the specific file in question.
