Latest Message<\/th>\nTitle: Some users may be unable to access the admin center or leverage Microsoft Entra to access other Microsoft 365 services<\/p>\n

User impact: Users may have been unable to access the Microsoft 365 admin center or Microsoft 365 services using Microsoft Entra.<\/p>\n

More info: Some users attempting to access other Microsoft 365 services, including but not limited to Microsoft Teams and Exchange Online, may have been unable to authenticate and access the services. Additionally, users might not have received Multi-Factor Authentication (MFA) messages when attempting to sign in.
Affected users may have encountered an error stating, “We are sorry, something went wrong. Please try refreshing the page in a few minutes. If the problem persists, please visit status.cloud.microsoft for updates regarding known issues.”<\/p>\n

Final status: Our analysis identified a portion of directory operations infrastructure which became imbalanced during a period of high traffic volume and caused authorization failures associated with impact. We’ve successfully rebalanced traffic across the affected infrastructure and confirmed after a period of monitoring that the impact is no longer occurring.<\/p>\n

Scope of impact: A portion of users attempting to access the Microsoft 365 services outlined in the ‘User impact’ and ‘More info’ sections of this communication may have been impacted. <\/p>\n

Preliminary root cause: A portion of directory operations infrastructure became imbalanced during a period of high traffic volume, which caused failures associated with impact.<\/p>\n

Start time: Wednesday, October 8, 2025, at 4:06 PM UTC<\/p>\n

End time: Wednesday, October 8, 2025, at 5:59 PM UTC<\/p>\n

Next steps:
– We’re analyzing volume trends and traffic management processes on the affected directory operations infrastructure to identify necessary refinements and increase resilience in the event of future instances of high traffic volume.<\/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
