Microsoft’s global outage eases after disrupting businesses

Microsoft's global outage affecting Outlook, Teams, and Copilot AI communication tools came to an end on Friday after a near 24-hour period of disruption that severely impacted online business operations. The incident, which also disrupted Copilot AI assistant, was caused by server issues and was being stabilized through software fixes, according to Microsoft.

The outage, which hindered essential functions like email, calendar management, and virtual meetings, affected numerous organizations worldwide, including government agencies in countries like Australia, Japan, and the United States. Airlines had to warn customers of communication lags due to the disruption. Microsoft confirmed they were not aware of any malicious activity or AI involvement.

The outage specifically impacted Exchange Online, a cloud-based email and scheduling hub. Services hosted on-premises by organizations were less affected. The outage is one of Microsoft's longest in history and the second disruption this year, raising concerns about the global reliance on major tech providers for both software and cloud infrastructure.

Microsoft shares saw a slight increase in afternoon trading, with the stock up around 8% for the year. Analysts noted the recurring nature of the issues, questioning whether such incidents could encourage customers to seek alternative options, despite the high switching costs associated with changing deeply embedded tools in daily operations.
