Microsoft outage disrupts Outlook and Teams for about 10 hours

A roughly 10-hour Microsoft outage disrupted Outlook, Teams and some other Microsoft 365 features on Nov. 12, affecting users across multiple regions and hitting businesses and government agencies worldwide. Microsoft linked the disruption to server problems and unusually heavy stress on systems, while Australia’s cyber security minister said the company did not believe it was facing a cyberattack. Downdetector showed more than 130,000 Outlook problem reports in the US at the peak and about 25,000 later in the evening. Microsoft said services tied to Exchange Online and email were affected, while features not reliant on Exchange Online largely kept working. The company said systems were showing early signs of stabilization as traffic was rerouted and capacity was restored.
