Microsoft Apologises Following Major Global Outage
Microsoft has issued a public apology after a widespread global outage left millions of customers unable to access essential online services for almost 24 hours.
The disruption, which began on Thursday, 12 November 2026, affected several widely used Microsoft products, including Outlook, Microsoft Teams, OneDrive, SharePoint and Microsoft 365. Users across multiple countries reported difficulties accessing emails, joining meetings and carrying out everyday workplace activities.
The outage caused significant disruption for businesses, government organisations, schools and healthcare providers that depend on Microsoft's cloud-based services to operate.
In a statement released on Friday, Microsoft said: "We are deeply sorry for the disruption this incident has caused our customers and partners." The company also acknowledged the trust customers place in its services and said it takes that responsibility extremely seriously.
What Caused the Microsoft Outage?
Microsoft has attributed the disruption to a technical issue involving an earlier network capacity upgrade.
According to the company, the problem surfaced following a more recent network change, which resulted in difficulties across its infrastructure. The issue caused some servers to become unavailable, placing additional pressure on the remaining systems.
Microsoft confirmed that the incident was not related to a cyberattack or artificial intelligence agents, addressing concerns and speculation surrounding the cause of the disruption.
The company said it had addressed the underlying issue and was continuing to restore services to affected customers and regions.
However, restoring operations proved challenging because of the scale of the disruption and the increased demand placed on systems during recovery.
Businesses and Public Services Affected Worldwide
The outage highlighted how heavily organisations around the world depend on Microsoft's digital infrastructure.
Businesses experienced interruptions to email communications, online meetings and file-sharing services. Employees who rely on Outlook and Teams for everyday operations faced difficulties communicating with colleagues and customers.
Healthcare providers, police services, schools and government departments were also among the organisations affected.
In the United Kingdom, some healthcare and public-sector organisations had to rely on alternative communication methods and contingency arrangements while Microsoft services remained unavailable.
The disruption demonstrated how a technical problem affecting a single major technology provider can have consequences across multiple industries.
Microsoft Begins Restoring Services
Microsoft said it had made significant progress towards restoring its services, reporting broad recovery and improved stability across its systems.
The company explained that services were being restored gradually, with engineers checking system stability at each stage before allowing normal traffic to return.
Although this approach extended the recovery period, Microsoft said it was necessary to ensure services could operate reliably.
Some customers continued to experience intermittent access problems and delays as systems recovered and outstanding email queues were processed.
The company has promised to publish a full post-incident report once its investigation is complete.
Concerns Over Dependence on Cloud Services
The incident has renewed discussions about the risks of organisations relying heavily on a small number of major cloud service providers.
Microsoft 365 is widely used by businesses and public institutions worldwide, making the availability of its services particularly important to everyday operations.
Although cloud-based platforms offer convenience, flexibility and improved collaboration, outages such as this demonstrate that even major technology companies are not immune to infrastructure failures.
Experts have highlighted the importance of organisations maintaining backup systems, alternative communication channels and effective disaster recovery plans.
What Happens Next?
Microsoft has apologised to affected customers and says it remains focused on ensuring services return to normal.
The company is expected to provide further details through its post-incident investigation, which should offer a clearer explanation of how the network issue developed and what measures will be introduced to prevent similar incidents in the future.
For millions of users and businesses, the immediate priority is a complete return to reliable service.
The outage serves as another reminder of how dependent modern society has become on digital infrastructure and how quickly everyday activities can be disrupted when essential online services become unavailable.
