Global Microsoft Outage Eases After Twenty Four Hours of Major Disruptions

A massive global outage affecting Microsoft Outlook, Teams, and Copilot began easing on Friday after lasting for more than 24 hours. The disruption crippled online communications for businesses and governments across the world, though Microsoft stated it still had no exact timeline for a full recovery.

Causes and Scope

Microsoft explained that server issues caused the incident and specifically hit features tied to Exchange Online, its cloud-based email and scheduling hub. The company ruled out artificial intelligence as the cause and said it was not aware of any malicious activity. A broader rollout of software fixes is now stabilizing the system. Organizations that host Microsoft services on their own servers were spared from the worst of the issues.

Global Impact

Ookla recorded more than 7.4 million reports worldwide, with complaints peaking at nearly 20,000 a minute. Government agencies in Australia, Japan, and the United States faced communication lags. The UK government worked with Microsoft after agencies like the NHS and London's Metropolitan Police were hit. Airlines in India, trading firms, shipping giants, and financial companies in Taiwan also suffered disruptions, with some firms resorting to fax machines or paper records.

Financial Estimates

Mario De Cicco of Morningstar DBRS estimated global insured losses between $300 million and $500 million. This figure stays well below the 2024 CrowdStrike outage that cost between $400 million and $1.5 billion. Microsoft shares closed flat at $523.88 on Friday, maintaining an 8% gain for the year.

Context

This incident marks the second major service disruption for Microsoft this year, following previous issues in January and October. Frequent outages raise fresh concerns about the heavy global reliance on just a few large technology providers for essential workplace software and cloud infrastructure.
