Microsoft has apologised to customers following a major global technology outage that disrupted its Microsoft 365 services, including Outlook, Microsoft Teams and Copilot, affecting businesses, government institutions and healthcare-related services across dozens of countries.
The disruption, which began on Thursday, November 12, 2026, continued into Friday as the technology company struggled to restore normal operations across its affected infrastructure.
According to outage-monitoring platform Downdetector, reports of service interruptions came from 74 countries and territories within approximately an hour of the incident beginning.
Microsoft acknowledged the disruption and said it was working to restore affected services, while warning that some customers could continue experiencing intermittent access problems and delayed email delivery during the recovery process.
The incident exposed the dependence of businesses, public institutions and other essential organisations on Microsoft’s cloud-based infrastructure for everyday operations.
Outlook, Teams and Copilot Among Services Affected
The outage affected several widely used Microsoft products, with Outlook experiencing some of the most significant disruptions.
Users reported difficulties accessing their email accounts, opening inboxes, sending messages and receiving communications through different connection methods.
Microsoft Teams, which organisations use for workplace communication, virtual meetings and collaboration, also experienced connectivity problems.
The company’s artificial intelligence assistant, Copilot, was among the other services affected.
The disruption extended beyond Microsoft’s directly operated applications, with some third-party services and technology companies reporting problems involving their Microsoft 365 integrations.
According to reports by the Associated Press, OpenAI and Anthropic also experienced disruptions affecting tools that rely on Microsoft’s infrastructure.
The widespread impact demonstrated how a problem affecting shared technology infrastructure can extend to multiple products and organisations, even when those services operate under different brand names.
Microsoft Apologises as Recovery Efforts Continue
Microsoft apologised for the inconvenience caused by the disruption as engineers continued working to restore affected systems.
The company initially reported that its infrastructure was experiencing elevated loads across multiple regions, contributing to connectivity problems.
However, the recovery process proved more complicated than initially anticipated.
In several updates, Microsoft indicated that some servers restored during its recovery efforts became unresponsive again when traffic returned.
The company subsequently explored alternative measures to increase system capacity, improve traffic management and stabilise affected infrastructure.
Microsoft also reported that its engineering teams were monitoring server performance and applying technical fixes to improve service reliability.
By Friday, November 13, the company reported progress in restoring services across North America, Europe and the Asia-Pacific region.
The Associated Press reported that Microsoft’s email queues had significantly reduced and were approaching normal levels, although some users continued experiencing intermittent access problems and delayed messages.
The company cautioned that improvements in service availability did not necessarily mean that every affected user had regained uninterrupted access.
74 Countries and Territories Reported Disruptions
The scale of the incident became increasingly apparent as outage reports emerged from different parts of the world.
Downdetector recorded reports from 74 countries and territories within approximately one hour of the disruption beginning.
The platform also reported that complaints involving Outlook rose to more than 2,000 times their normal level.
In the United States, the number of reports concerning Outlook problems reached approximately 130,000 at the height of the disruption, according to reports by the Associated Press and other international media organisations.
Countries across Europe, Asia, Africa and the Americas reported service interruptions.
The impact was particularly significant for organisations that depend heavily on Microsoft’s communication and productivity tools to coordinate their daily operations.
However, the 74-country figure represents locations from which outage reports were recorded by Downdetector, rather than an independently confirmed count of countries where every Microsoft service was affected.
Microsoft has not disclosed the exact number of individual users affected by the incident.
Healthcare Services and Pharmacies Experience Disruptions
One of the most concerning aspects of the outage was its impact on healthcare-related communication and administrative systems.
In the United Kingdom, several National Health Service organisations reported problems accessing Microsoft services, including Outlook and Teams.
The disruption affected staff communication, administrative operations and some digital systems used by healthcare providers.
According to The Guardian, healthcare workers experienced difficulties accessing email and other information technology systems required for their daily responsibilities.
Some pharmacies also reported communication problems involving general practitioner practices, raising concerns about possible delays in prescription-related processes.
The National Pharmacy Association warned that disruption to email systems could affect communication between pharmacies, GP practices and patients.
Community Pharmacy England also issued guidance advising pharmacy teams to prepare for possible interruptions involving Microsoft-dependent systems.
However, the disruption did not mean that all healthcare services had stopped operating.
Several NHS organisations advised patients to continue attending scheduled appointments while using telephone communication where email services were unavailable.
The Isle of Wight NHS Trust, for example, said the incident had affected internal systems, particularly staff email and administrative services, but that ambulance operations and hospital patient care were continuing.
The distinction was important because the incident primarily affected digital communication and administrative infrastructure rather than establishing a widespread suspension of emergency medical services.
Government Agencies and Businesses Also Affected
The disruption extended into government institutions and private businesses that depend on Microsoft 365 for official communication and administrative activities.
In Singapore, government technology authorities reported problems involving government email services and said they were working with Microsoft to address the disruption.
The Philippines’ Supreme Court also reported that the outage had affected some of its operations, including email responses.
In Japan, government officials acknowledged the impact on information technology infrastructure and said alternative communication arrangements were being considered.
Australian government agencies also reported disruption.
Australia’s Home Affairs Minister, Tony Burke, said he had been informed by Microsoft that the incident was not believed to be a cyberattack.
Businesses also experienced interruptions involving customer communication, internal coordination and other workplace activities.
Some organisations resorted to alternative communication channels to maintain operations while Microsoft’s services remained unstable.
The incident illustrated the importance of having backup communication arrangements that do not depend entirely on one technology provider.
Microsoft Says Outage Was Not a Cyberattack
Concerns about the possibility of a cyberattack emerged as the disruption spread across multiple regions and affected several major services.
However, Microsoft said there was no indication that malicious activity or a cybersecurity incident had caused the outage.
Charles Lamanna, Microsoft’s Executive Vice President of Copilot, Agents and Platform, also indicated that the incident was not believed to be the result of malicious activity.
Australian authorities similarly reported that Microsoft did not believe it was dealing with a cyberattack.
Nevertheless, the company had not published a definitive root-cause explanation in the updates available during the recovery period.
Microsoft’s technical updates pointed to infrastructure problems, elevated server loads and difficulties restoring affected systems.
The company also worked on reversing a network-related change as part of its recovery measures, although it had not established publicly whether that change was ultimately responsible for the incident.
Microsoft said it would provide a more detailed post-incident report after completing its recovery efforts.
Outage Raises Questions About Global Dependence on Big Technology Companies
The incident has renewed discussions about the risks associated with organisations relying heavily on a small number of major technology providers.
Microsoft 365 is widely used by businesses, educational institutions, government agencies and healthcare organisations for email, document management, meetings and collaboration.
The Associated Press reported that Microsoft had more than 450 million paid commercial Microsoft 365 subscriptions.
That extensive adoption makes the company’s infrastructure an important component of everyday business and institutional operations across the world.
Technology experts have warned that services such as Outlook, Teams and Copilot may appear to function independently, but can rely on shared infrastructure.
Consequently, a failure affecting a common infrastructure component can disrupt several applications simultaneously.
The incident also raises questions about the resilience of organisations that depend on cloud-based platforms for essential operations.
For businesses, an inability to access email or collaboration tools can delay transactions, interrupt customer service and affect communication between employees.
For public institutions, similar disruptions can complicate administrative responsibilities and communication with citizens.
Healthcare organisations face additional challenges because digital communication can support appointment coordination, prescription-related processes and information sharing among medical professionals.
These risks make operational continuity planning increasingly important.
Why the Incident Matters to Africa
The outage also carries lessons for African businesses, governments and institutions as digital transformation continues across the continent.
Many organisations in Africa increasingly depend on international cloud providers and digital productivity platforms to manage communication, store information and deliver services.
Although the available reports do not establish the precise level of disruption experienced by African users, the global scale of the incident demonstrates that dependence on external technology infrastructure can create operational vulnerabilities across geographical boundaries.
For African businesses, maintaining alternative communication channels, secure data backups and tested business continuity arrangements can help reduce the consequences of similar disruptions.
Government institutions and healthcare providers also need contingency systems that allow essential services to continue when third-party technology platforms become unavailable.
The incident does not necessarily mean organisations should abandon cloud services. Rather, it highlights the importance of ensuring that critical operations are not entirely dependent on a single provider.
What Happens Next?
Microsoft’s immediate priority is to complete the restoration of affected services and ensure that its infrastructure can handle normal traffic without further instability.
The company reported improving service availability and reduced email delivery backlogs during Friday’s recovery efforts.
However, intermittent access problems and delayed messages remained possible for some users in the updates published during the recovery period.
Microsoft is also expected to provide a post-incident report explaining the underlying cause of the disruption and the measures it intends to implement to prevent similar incidents.
The findings will be important for businesses, government agencies and other organisations assessing their dependence on Microsoft 365 and related cloud services.
For customers, the incident serves as a reminder that even widely trusted technology platforms can experience significant interruptions.
As organisations increasingly move their operations online, the ability to maintain essential services during technology failures is becoming just as important as the digital tools they use.
