Latest Message<\/th>\nTitle: Users are unable to submit a prompt in Microsoft 365 Copilot Chat and receive an error message<\/p>\n

User impact: Users are unable to submit a prompt in Microsoft 365 Copilot Chat and receive an error message.<\/p>\n

More info: Microsoft 365 Copilot Chat returned the following error message: “Something went wrong.” Some users were unable to submit a prompt in Microsoft 365 Copilot Chat and received an error message. Some users saw Copilot responses being provided successfully at first but then encountered an error message that overridden and removed the response after it had initially been generated successfully.<\/p>\n

Final status: We have confirmed with impacted users that the issue has been fully resolved. We appreciate your organization’s understanding and patience while we worked on addressing this incident. <\/p>\n

Scope of impact: This issue affected some users when they tried to submit a prompt in Microsoft 365 Copilot Chat. This section was updated as our investigation continued.<\/p>\n

Start time: Friday, June 12, 2026, at 4:00 AM UTC<\/p>\n

End time: Monday, June 15, 2026, at 10:40 PM UTC<\/p>\n

Preliminary root cause: We’ve identified a code regression which was causing impact during prompt submission. We subsequently fixed the issue via a configuration update to disable the impacting portion of code. <\/p>\n

Next steps:
– We’re reviewing our change management practices to identify areas of improvement to prevent similar events from occurring in the future.
– We’re analyzing our incident response readiness to find methods to reduce the time to mitigate and improve pre-incident detection signals. <\/p>\n

We’ll provide a preliminary Post-Incident Report within two business days and a final Post-Incident Report within five business days.<\/td>\n<\/tr>\n
