Latest Message<\/th>\nTitle: Some users in the United States may have been unable to access multiple Microsoft 365 services<\/p>\n

User impact: Users may have been unable to access multiple Microsoft 365 services.<\/p>\n

More info: Impacted services included but weren’t limited to:
– Microsoft Teams
– Exchange Online
– Microsoft 365 Suite<\/p>\n

Specifically, users may have experienced sudden disconnects, increased latency, or intermittent access issues.<\/p>\n

Final status: We’ve determined that an Azure infrastructure connection became overloaded with user traffic due to insufficient load distribution, causing latency and disconnects across multiple Microsoft 365 services. We’ve redirected affected traffic to alternate infrastructure and confirmed impact is no longer occurring after a period of monitoring.<\/p>\n

Scope of impact: Impact was specific to some users in the United States attempting to access Microsoft 365 services.<\/p>\n

Start time: Tuesday, April 7, 2026, at 1:20 PM UTC<\/p>\n

End time: Tuesday, April 7, 2026, at 1:50 PM UTC<\/p>\n

Root cause: An Azure infrastructure connection became overloaded with user traffic due to insufficient load distribution, causing latency and disconnects across multiple Microsoft 365 services.<\/p>\n

Next steps:
– We’re analyzing traffic performance data and trends on the affected infrastructure connection to help prevent this problem from happening again.<\/p>\n

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