Microsoft service outage leaves thousands of users without access to email and affects Copilot

A major outage in Microsoft's infrastructure has disrupted various services, primarily affecting Outlook email and the Copilot AI assistant. Users are unable to access their mailboxes through multiple methods, with over 65,000 complaints reported on Downdetector. Initially thought to impact only the Americas, issues have spread globally, including in Portugal. Microsoft Teams is experiencing access difficulties, and a configuration change in Word Online has caused compatibility problems. The Copilot AI has also faced instability, with users reporting response failures. Microsoft is investigating the Exchange Online failure and advises users to avoid logging out to prevent further access issues.
