Microsoft Outlook Global Outage Hits Users Across 74 Countries
A major Microsoft outage has disrupted Outlook, Microsoft 365 and AI tools including Copilot, ChatGPT and Claude for tens of thousands of users worldwide.
A widespread technical failure struck Microsoft's Outlook email service, leaving tens of thousands of users across 74 countries unable to access their messages. The outage also affected the broader Microsoft 365 suite of productivity tools, which includes Word, Excel, Teams and other applications used daily by businesses and individuals around the world.
Several AI assistants were caught up in the disruption as well. Users of Microsoft's own Copilot tool reported problems, and third-party AI services including ChatGPT and Claude also experienced interruptions, likely because these platforms rely on shared cloud infrastructure.
Microsoft confirmed it was aware of the incident and said its engineers were actively investigating the root cause. The company did not immediately provide a timeline for a full restoration of services.
Outages of this scale are tracked in real time by independent monitoring platforms such as Downdetector, which aggregates user reports to map the geographical spread and volume of disruptions. Reports surged rapidly across Europe, North America, Asia and Africa, confirming the global reach of the failure.
For Mauritius, where Microsoft 365 is widely used in the public sector, financial services, and by multinational companies operating from the island's freeport and business park zones, the outage would have had a direct impact on day-to-day operations. Many Mauritian businesses rely on Outlook as their primary email client and on Teams for internal communication, making a prolonged outage a significant operational risk.
What this means: When a single technology provider supplies email, cloud storage, video calls and AI tools to millions of organisations, a single point of failure can cascade across entire economies. This outage is a reminder of how deeply businesses in Mauritius and globally depend on a small number of cloud platforms, and why IT continuity planning, including backup email systems and offline document access, is increasingly important. Companies that have diversified their communication tools across more than one provider were better placed to keep working through the disruption.
Microsoft has experienced several high-profile outages in recent years, including a major global incident in 2024 linked to a faulty software update from cybersecurity firm CrowdStrike, which grounded flights and disrupted hospitals worldwide. This latest event underlines the ongoing vulnerability of cloud-dependent infrastructure.
