Title: Users are unable to access Microsoft 365 Copilot Chat or portal.office.com
User impact: Users are unable to access Microsoft 365 Copilot Chat or portal.office.com.
More info: Admins may have been able to access the Microsoft 365 admin center via admin.cloud.microsoft as a temporary solution. Additionally, Copilot in Microsoft Teams was not impacted and could have been leveraged in the interim while we mitigated the issue.
Final status: We’ve successfully rolled back the change throughout the affected infrastructure, and we've confirmed with previously affected users that the impact is mitigated.
Scope of impact: Any user or admin may have been affected by this event.
Start time: Thursday, June 11, 2026, at 8:00 PM UTC
End time: Thursday, June 11, 2026, at 9:56 PM UTC
Preliminary root cause: We've identified an issue with a recent deployment which is contributing to impact. We will provide more information in our Post-Incident Report.
Next steps: - We're analyzing the recent deployment to identify why this issue occurred and how to prevent it from happening again in the future.
- We're reviewing our change management processes to determine areas of improvement.
We'll provide a preliminary Post-Incident Report within two business days and a final Post-Incident Report within five business days.
