Microsoft Withdraws Copilot Domain Exclusion Feature One Week After Launch

Microsoft has rolled back its newly launched "Domain Exclusion" feature for Microsoft 365 Copilot just one week after its release. This feature allowed IT administrators to block specific domains from being used in Copilot's web-grounded responses. The rollback highlights the challenges of enterprise AI governance and the preference of IT administrators for allowlist controls over tedious blacklist management. It shows how user feedback can quickly force major software vendors to rethink their security and compliance designs. The withdrawn feature allowed admins to exclude up to 1,000 domains using PowerShell scripts, but administrators found manually tracking bad sites impractical and the limit too restrictive. Microsoft has not provided a timeline for a replacement feature but stated they are actively evaluating next steps.
