Microsoft outage disrupts Outlook, Teams, and Copilot worldwide

A major Microsoft outage affecting Outlook, Teams, and Copilot has exceeded 12 hours, disrupting communications for businesses and governments worldwide. Microsoft attributes the issue to server problems and reports no malicious activity, with signs of stabilization emerging after broad fixes. The disruption has impacted government agencies in Australia, Japan, and the US, plus stockbrokers, corporate earnings delays, and airline customer alerts. In Taiwan, one financial firm resorted to fax machines for trade confirmations, while European companies like Aviva and Maersk activated contingency plans. This marks the second Microsoft 365 outage this year, following incidents in January and last October, plus an Azure cloud disruption last month. Analysts note investors may tolerate the issue, but recurring reliability problems could prompt IT departments to reconsider single-provider dependence.
