Microsoft outage disrupts 365, Outlook, Teams for users in US, Canada, Europe

Tens of thousands of users reported outages affecting Microsoft 365, Outlook, Teams, and other Microsoft services, preventing access or causing unstable connections. The disruption began around 1 a.m. Hanoi time on November 13 and primarily impacted users in the US, Canada, and parts of Europe. Downdetector recorded over 130,000 outage reports for Outlook, more than 45,000 for Microsoft 365, and over 10,000 for Microsoft Store in the US alone. Microsoft confirmed the issue, initially citing high load on infrastructure before explaining that some servers were "not operating normally unexpectedly," causing pressure on remaining systems. The company stated servers were stabilizing and traffic was being rerouted. The outage also affected third-party partners, including OpenAI and Anthropic, which reported issues with Microsoft connectors. US electric truck maker Workhorse Group delayed its Q3 earnings report due to the disruption. This incident follows a global Azure outage on October 29 that lasted over eight hours.
