Latest Message<\/th>\nTitle: Users may have received no response when prompting Microsoft 365 Copilot Chat using the Claude Opus model <\/p>\n

User impact: Users may have received no response when prompting Copilot Chat using the Claude Opus model. <\/p>\n

More info: When users attempted to prompt Copilot Chat using the Claude Opus model, they may have received an error that stated, “We’re experiencing high demand. Please try again later.” <\/p>\n

Final status: After applying our configuration changes to rebalance request traffic, we’ve confirmed after a period of monitoring that the issue was successfully resolved. <\/p>\n

Scope of impact: Any user prompting Copilot Chat using the Claude Opus model may have been impacted. <\/p>\n

Start time: Monday, June 01, 2026, at 1:00 PM UTC <\/p>\n

End time: Thursday, June 04, 2026, at 9:00 PM UTC <\/p>\n

Root cause: An increase in request traffic was causing the portion of infrastructure responsible for facilitating the responses to prompts using Claude Opus in Copilot Chat to operate in a suboptimal state. <\/p>\n

Next steps:
– We’re reviewing opportunities to improve our monitoring and alerting for high request traffic scenarios to improve response time and better prevent similar future impact. <\/p>\n

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