Hi 顾 泽
Based on your description, I understand that your tenant has been flagged for a potential violation of the Microsoft Acceptable Use Policy (AUP) as defined in the Product Terms.
AUP enforcement actions are typically triggered by automated detection systems and reviewed by a specialized internal team. Forum moderators do not have visibility into the specific cause of this action and are not able to override these restrictions or unblock the affected OneDrive.
Since this cannot be handled through the forum, the appropriate next step is to submit a support request. You can do this by selecting Contact support on the SharePoint Acceptable Use Policy page in the Microsoft 365 admin center, which can route the case to the responsible enforcement team for review and guidance on remediation.

Thank you for your understanding.
