Latest Message<\/th>\nTitle: Users’ queries to Microsoft 365 Copilot Chat may return no response, and users receive an error <\/p>\n

User impact: Users’ queries to Copilot Chat may have returned no response, and users received an error. <\/p>\n

More info: When users attempted to query Copilot Chat, some of their queries may have returned no response and instead, users may have received an error that stated, “Something went wrong.” <\/p>\n

Final status: We’ve applied configuration changes to rebalance the request traffic and confirmed using our service health telemetry that the impact is remediated. <\/p>\n

Scope of impact: Any user that attempted to query Copilot Chat may have been impacted. <\/p>\n

Start time: Thursday, September 3, 2026, at 6:30 AM UTC <\/p>\n

End time: Thursday, September 3, 2026, at 7:45 PM UTC <\/p>\n

Root cause: An increase in request traffic to the portion of service infrastructure responsible for facilitating Copilot Chat responses prevented the service from being able to efficiently process requests. <\/p>\n

Next steps:
– We’re continuing to investigate the source of the increased request traffic, so that we can determine how to prevent similar impact to users’ Copilot Chat queries in the future. <\/p>\n

This is the final update for the event.<\/td>\n<\/tr>\n
