Investigating

We’re currently experiencing delays in our Advanced Threat Protection (ATP) service when scanning email attachments. As a result, some emails may be temporarily deferred with the status: “Pending Scan.”

Our engineering team is actively investigating the root cause and working to restore normal scan times as quickly as possible. We’ll continue to provide updates as we make progress.

We appreciate your patience and understanding.
