Latest Message<\/th>\nTitle: Some users may be unexpectedly disconnected when accessing multiple Microsoft 365 services<\/p>\n

User impact: Users may have been unexpectedly disconnected when accessing multiple Microsoft 365 services.<\/p>\n

More info: Affected Microsoft 365 services included but may not have been limited to the following:<\/p>\n

– Microsoft Teams
– Outlook<\/p>\n

Final status: After analyzing the spike in user reports for affected Microsoft 365 services, we’ve determined that a portion of our Microsoft 365 network infrastructure, responsible for facilitating access to connected services, was operating in an unhealthy state and unable to process user requests effectively. We’ve removed the offending infrastructure from our service rotation, and after a period of monitoring service health telemetry, we’ve confirmed users can connect to Microsoft 365 services as expected.<\/p>\n

Scope of impact: Some users may have been unexpectedly disconnected when accessing multiple Microsoft 365 services including Microsoft Teams and Outlook.<\/p>\n

Start time: Wednesday, August 27, 2025, at 1:30 PM UTC<\/p>\n

End time: Wednesday, August 27, 2025, at 2:24 PM UTC<\/p>\n

Root cause: A portion of our Microsoft 365 network infrastructure, responsible for facilitating access to connected services, was operating in an unhealthy state and unable to process user requests effectively.<\/p>\n

Next steps:
– We’re analyzing the offending portion of Microsoft 365 network infrastructure to determine how it came to operate in an unhealthy state. This analysis will help us to determine what actions we can take to improve the resilience of our service infrastructure to prevent similar impact from occurring in future.<\/p>\n

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