Microsoft 365 outage affects Teams, SharePoint and other services
Microsoft said thousands of users in North America were affected as Teams, Outlook and other 365 services showed degradation.
On Thursday, July 23, 2026, thousands of users across North America reported widespread outages affecting Outlook, Teams, and Azure services.
Microsoft attributed the disruption to an undisclosed recent network change that began at approximately 14:44 UTC, prompting the company to roll back the update.
Customers of the Azure West US region experienced intermittent connectivity failures and increased latency, impacting Application Gateway, Azure Kubernetes Service , and Virtual WAN.
By 18:47 UTC, Microsoft reported recovery progress, stating, "Telemetry across services are continuing to show signs of recovery," and advised that "Customer should be observing recovery at this time."
BuyDowndetector also tracked reports for other services including Amazon Web Services and Cloudflare around the same time, though Microsoft's degradation was isolated to specific network paths.
