Updated September 9, 2026: We are removing this post as the feature described below is now being tracked in MC1462915. You can safely disregard this message.<\/p>\n

[What and why]<\/b><\/p>\n

Microsoft 365 Copilot Chat in Microsoft Edge is updating the endpoint used for the compliant Copilot Chat experience in the Edge sidebar. The endpoint is changing from outlook.office.com\/hosted\/semanticoverview\/Users<\/code> to cr.m365copilotapp.svc.cloud.microsoft<\/code>.<\/p>\n

This change aligns Microsoft 365 Copilot Chat in Edge with the current endpoint architecture and documented Microsoft Edge allowlist requirements. Organizations that manage network allowlists or blocklists may need to update their configurations to ensure continued access to Microsoft 365 Copilot Chat in Edge.<\/p>\n

        • Organizations that explicitly allow or block network endpoints for Microsoft 365 Copilot Chat in Edge may need to update their configurations.<\/li>\n
        • If the new endpoint is blocked or not allowlisted, users may experience issues accessing Microsoft 365 Copilot Chat in Edge.<\/li>\n
        • No changes are expected for organizations that do not manage endpoint allowlists or blocklists for this service.<\/li>\n<\/ul>\n
