Microsoft Outage: 74 Countries Hit as Services Down 24 Hours
A major Microsoft outage disrupted Outlook, Teams and Copilot for over 24 hours across 74 countries, with thousands of users reporting failures.
A widespread Microsoft outage knocked out key business services for more than 24 hours, affecting users across 74 countries and territories and triggering thousands of fault reports from individuals and organisations around the world.
Services including Outlook, the email platform used by millions of professionals, Teams, the workplace messaging and video-call tool, and Copilot, Microsoft's artificial intelligence assistant, were all affected during the incident. Users in the United States, the United Kingdom and the Asia-Pacific region were among the hardest hit, based on the volume of reports logged on outage-tracking platforms.
Microsoft attributed the disruption to an overload issue within its infrastructure, though the company did not immediately provide a detailed technical breakdown of the root cause. The scale of the event placed it among the most significant cloud-service failures in recent years.
For many businesses, the timing was particularly costly. Outlook and Teams sit at the centre of daily operations for companies of all sizes, handling internal communication, client correspondence, meetings and file sharing. A prolonged outage of more than a day meant employees were unable to access emails, join scheduled calls or retrieve documents stored on the platform.
Mauritius was not spared. Banks and financial regulators on the island reported disruptions to their systems during the outage period, underlining how deeply global cloud infrastructure is now embedded in the local economy. With the financial sector and many businesses relying on Microsoft 365 services, any failure at the data-centre level in Europe or the United States can quickly cascade to offices in Port Louis.
This is not the first time a large-scale technology failure has exposed the vulnerability of modern digital infrastructure. Similar events, including a previous Microsoft 365 outage that affected roughly 70 countries, have prompted calls from regulators and businesses alike to maintain backup communication systems and disaster-recovery plans.
What this means: For everyday users in Mauritius and beyond, this outage is a reminder that cloud services, however reliable they appear in normal conditions, can fail simultaneously across entire regions. Businesses that depend entirely on a single provider for email, meetings and file storage face serious operational risk when that provider goes down. Experts recommend that organisations keep alternative communication channels in place, ensure critical documents are backed up locally, and have a clear protocol for the hours or days when their primary tools become unavailable.
Microsoft has not yet released a full public post-incident report detailing the precise cause or the total number of users affected globally.
