Microsoft Global Outage Disrupts Outlook, Teams and Copilot Across 74 Countries
A widespread Microsoft outage has disrupted access to Outlook, Teams and Copilot across 74 countries, affecting software used by approximately 450 million work accounts. The disruption lasted more than five hours, with Microsoft's Exchange Online email service at the centre of the incident. Microsoft had not confirmed the cause at the time of the report, according to information published by Coin Bureau.
Exchange Online Failure Triggers Widespread Disruption
The outage was linked to Exchange Online, Microsoft's cloud-based email service that delivers Outlook email to businesses and organizations. The system reportedly began experiencing failures around midday Eastern time on Thursday, triggering widespread problems for users who depend on Microsoft's services for daily communications and workplace operations.
The scale of the disruption became increasingly apparent as reports of service problems surged. By 1:25 PM, the number of reported incidents had climbed from fewer than 15 per minute to 19,650, according to figures cited in Coin Bureau's X post.
Outlook-related reports were particularly severe, reaching levels approximately 2,000 times higher than normal. The figures illustrate the extent of the disruption affecting Microsoft's email infrastructure, although the source did not specify how many individual users were directly affected or whether all reported incidents involved complete service interruptions.
Outlook, Teams and Copilot Affected Across 74 Countries
The incident extended beyond Microsoft's email platform, with Outlook, Teams and Copilot all reported as affected. The disruption was reported across 74 countries, highlighting the international reach of Microsoft's cloud-based workplace ecosystem.
The affected products serve different but closely connected business functions. Outlook provides email and calendar services, Teams supports workplace communication and collaboration, while Copilot offers Microsoft's AI-powered assistance tools. Their reported disruption illustrates how problems involving a central cloud service can affect multiple products used within business environments.
Coin Bureau said the affected software is used by approximately 450 million work accounts. That figure represents the reported reach of the software ecosystem, rather than a confirmed count of accounts that lost access during the outage.
Government and Healthcare Organizations Report Problems
The disruption also affected organizations responsible for essential public and healthcare services. According to the report, a US state government and two hospital systems in Michigan lost access to email.
The reported interruptions demonstrate how dependence on cloud-based communication infrastructure extends beyond conventional corporate workplaces. Government agencies and healthcare providers also rely on email systems to coordinate administrative activities and exchange information.
However, the source did not identify the affected state government markets or the two Michigan hospital systems. It also did not report whether the organizations experienced disruptions to other operational systems or how long their email access remained unavailable.
Microsoft Yet to Confirm the Cause
Despite the scale and duration of the incident, Microsoft had not confirmed what caused the disruption at the time covered by Coin Bureau's report. The outage had continued for more than five hours, leaving the underlying technical issue unresolved in the available information.
The reported timeline places the beginning of Exchange Online problems around midday Eastern time on Thursday, followed by a sharp increase in incident reports. By 1:25 PM, reports had reached 19,650, while Outlook-related complaints were running approximately 2,000 times above normal.
The incident's reported reach across 74 countries, its impact on Outlook, Teams and Copilot, and the loss of email access at a US state government and two Michigan hospital systems underline the scale of the disruption described by Coin Bureau.
