Report the Unfamiliar Account to Your Microsoft 365 Administrator

Document the suspicious file ownership and contact your university's IT department so they can investigate and verify the account.

In enterprise and educational Microsoft 365 environments, automated service accounts are sometimes created for security auditing, compliance, or Copilot integration. However, to ensure your account is not compromised, it must be verified by an administrator.

Review file access details

Right-click the affected file, select 'Manage access', and note down all the sharing, audit, and ownership details currently applied to the file.

Contact your IT helpdesk

Send the screenshots and details to your university's Microsoft 365 administrator or IT support team, requesting them to check whether this account is an authorized security identity.

Administrator Verification Required: Only an authorized Microsoft 365 administrator has the backend access needed to trace the origin of the account and confirm if it is a legitimate service.
