Microsoft 365 Copilot Chat in Microsoft Edge will change its endpoint to cr.m365copilotapp.svc.cloud.microsoft by late September 2026. Organizations managing network allowlists or blocklists must update configurations to maintain access. No changes affect those not managing endpoint restrictions. Review and update settings accordingly.
