Microsoft is facing a major global service disruption affecting thousands of users and businesses after technical problems disrupted access to some of its widely used platforms, including Teams, Outlook, OneDrive and its artificial intelligence tool, Copilot.
The outage has affected Microsoft 365 services, leaving individuals and organisations in different parts of the world struggling to access essential workplace applications and carry out routine business activities.
Microsoft has acknowledged the disruption and says its technical teams are working around the clock to restore normal operations.
In a series of updates shared on X, the technology company said it had recorded positive results from its recovery efforts and was taking urgent steps to address the problem.
However, the company cautioned that restoring all affected services could take time, particularly as some systems remained unstable.
Data from internet monitoring platform Downdetector showed that reports of problems with Outlook peaked at nearly 140,000 globally at around 18:00 GMT on Thursday, highlighting the scale of the disruption.
The outage has generated concerns among businesses and individuals who depend on Microsoft’s services for communication, document management, online meetings and other essential activities.
The BBC understands there is currently no indication that the disruption was caused by a cyberattack.
Microsoft 365 is one of the most widely used productivity platforms globally, providing businesses, government institutions and individuals with access to a range of digital tools.
Its services include Outlook for email communication, Teams for virtual meetings and workplace collaboration, and OneDrive for storing and sharing files online.
The platform has become particularly important for international organisations with employees and business partners operating across different countries and time zones.
For many companies, the disruption has affected their ability to communicate effectively, access important documents and coordinate activities with colleagues.
Microsoft confirmed that some users may experience difficulties viewing certain files, accessing information within their calendar applications and using other features connected to its services.
The company’s artificial intelligence platform, Copilot, has also experienced problems, with some users unable to access its full range of functions.
Copilot has become an important productivity tool for businesses and professionals who rely on artificial intelligence to assist with writing, analysing information, preparing documents and completing workplace tasks.
The disruption has therefore extended beyond traditional email and communication services, affecting organisations that have increasingly incorporated AI-powered tools into their daily operations.
Despite the widespread problems, Microsoft indicated that some features were still functioning.
The company said messaging services and online meetings were largely operational, although users could continue to experience difficulties with other aspects of the platform.
Explaining the cause of the outage, Microsoft said a number of servers had become unexpectedly unavailable, placing additional pressure on the remaining systems.
The loss of several servers affected the capacity of the network to manage normal levels of demand, resulting in connectivity problems across different services.
A Microsoft spokesperson apologised for the inconvenience caused and assured customers that efforts were underway to restore the affected systems.
“We appreciate our customers’ patience while we work to restore services as soon as possible,” the spokesperson said.
However, in a subsequent update, the company warned that some services which had initially been restored could become unresponsive again.
It also indicated that customers in any region could experience further difficulties as engineers continued working to stabilise the systems.
The warning raised concerns that users who had regained access to certain applications might experience additional interruptions before the situation was fully resolved.
Reports of service disruptions have come from several parts of the world, including the United States, Japan and Singapore.
The geographical spread of the outage has highlighted the extent to which businesses and individuals depend on Microsoft’s cloud-based infrastructure for everyday operations.
The impact has also extended to other major technology companies, including artificial intelligence firms Anthropic and OpenAI, which rely on Microsoft’s systems for some of their services.
OpenAI, the company behind ChatGPT, confirmed that it was investigating a technical issue affecting its connections to Microsoft’s services.
The company explained that the problem had caused some of its tools to operate differently from expected, adding another layer of disruption for users relying on AI-powered applications.
The incident demonstrates how technical problems affecting major cloud and technology infrastructure providers can have consequences beyond their immediate customer base.
As more companies integrate cloud computing and artificial intelligence into their operations, disruptions affecting one major provider can potentially affect several other businesses and digital services connected to its systems.
The latest incident is also raising questions about the reliability of large-scale cloud infrastructure and the challenges technology companies face in maintaining uninterrupted services for millions of users.
Microsoft experienced another major disruption last month when an outage involving its Azure cloud platform affected the company’s productivity services and businesses around the world.
Azure provides cloud computing infrastructure used by organisations to host applications, store data and operate digital services.
The latest problems have renewed attention on the risks associated with depending heavily on centralised cloud platforms, particularly when technical failures affect multiple services simultaneously.
The disruption has also had consequences for businesses outside the technology sector.
Electric truck manufacturer Workhorse Group, which was scheduled to release its third-quarter financial results on November 12, postponed the announcement until November 16.
The company attributed the decision to business disruptions resulting from the global Microsoft outage.
The development illustrates how technical failures involving major digital service providers can affect business operations, financial reporting and other activities that depend on reliable access to online systems.
For businesses with employees working remotely or across different locations, the disruption has created additional challenges in maintaining communication and meeting operational deadlines.
Microsoft has continued to monitor the situation while its engineers work to restore services and improve system stability.
Customers have been advised to monitor the company’s official communication channels for further updates as recovery efforts continue.
Although Microsoft has reported progress, the possibility of renewed interruptions means that users may still experience difficulties accessing some applications.
The company has not indicated that all affected services have returned to normal, leaving businesses and individuals waiting for a complete restoration of the platform.
The incident serves as another reminder of the growing dependence of the global economy on digital infrastructure and the widespread consequences that can follow when essential technology services experience major disruptions.
