Technology giant Microsoft has admitted that efforts to resolve a widespread global outage affecting its services are not progressing as expected, leaving tens of thousands of users unable to access essential communication and productivity platforms across 74 countries.

The disruption, which has affected Microsoft Outlook, Teams, Exchange Online and its artificial intelligence platform, Copilot, has lasted more than eight hours, causing difficulties for businesses, government agencies, healthcare institutions and other organisations that depend on Microsoft’s technology.
The company disclosed that its infrastructure was experiencing an unusually heavy workload across several regions, with some servers becoming unavailable and placing additional pressure on the remaining systems.
Although Microsoft initially reported positive results from efforts to restore affected services, it subsequently acknowledged that the changes introduced to resolve the problem were not producing the expected outcome.
In its latest update, the company stated that the measures intended to improve service availability were “not taking as expected”.
Microsoft explained that its engineers were testing alternative solutions to enable more users to reconnect without overwhelming its infrastructure.
The company also warned that services which had temporarily resumed operations could become unresponsive again when additional users attempted to access them.
Earlier, Microsoft had announced that its technical teams were “seeing positive results” while restarting affected systems and monitoring their performance.
However, the latest development indicated that the recovery process remained unstable.
The outage began shortly after 16:15 GMT on Thursday, November 12, 2026, according to internet service monitoring platform Downdetector.
Within approximately one hour, reports of service disruptions had spread across 74 countries.
Downdetector recorded nearly 140,000 reports of problems involving Microsoft Outlook globally at around 18:00 GMT, representing more than 2,000 times the normal reporting level.
Although the number of reported problems subsequently declined, the monitoring platform still recorded more than 28,000 reports as Microsoft continued its restoration efforts.
The widespread disruption has affected access to Microsoft 365, a suite of subscription services used by individuals, businesses and public institutions around the world.
According to Microsoft’s published figures, more than 430 million people use Microsoft 365 applications, including Outlook and Teams.
The company also states that more than 90 per cent of Fortune 500 companies use its artificial intelligence assistant, Copilot.
Industry tracking platforms estimate that between three million and four million companies rely on Microsoft 365 services.
The scale of the disruption has therefore raised concerns about the dependence of businesses and public institutions on major technology infrastructure providers.
Among the affected services is Exchange Online, Microsoft’s cloud-based email system that supports Outlook.
Many users have been unable to access their email accounts or communicate through the platform.
Microsoft also disclosed that some customers may be unable to view certain files or details within their calendar applications.
Its AI-powered Copilot service has experienced disruptions, while Teams users have reported connectivity problems.
However, the company clarified that messaging and online meetings remained largely functional despite the wider service difficulties.
Explaining the technical challenges, Microsoft attributed the disruption to “elevated load” on its infrastructure across multiple regions.
The company stated that the problem was not simply the result of increased user traffic.
Rather, several servers had become “unexpectedly unavailable”, forcing the remaining infrastructure to handle workloads beyond their normal capacity.
According to Microsoft, a critical part of its affected infrastructure was “becoming overwhelmed”, contributing to the continuing service disruption.
The company maintained that its engineers were working to restore stability and identify the conditions responsible for the failures.
Meanwhile, the outage has extended beyond Microsoft’s own applications, affecting technology companies whose products depend on connections to its services.
Artificial intelligence company OpenAI disclosed that it was investigating an issue affecting its connections to Microsoft services, which had caused some of its tools to malfunction.
Another AI company, Anthropic, also confirmed identifying a problem involving its connections to Microsoft 365 services.
The developments illustrate the wider consequences of infrastructure disruptions involving technology providers whose systems are integrated with other platforms.
Australia has emerged as one of the countries experiencing operational difficulties, particularly because the outage continued into Friday morning in the country.
Several government services have reported problems linked to the disruption.
Service NSW, which provides access to government services in New South Wales, advised customers to postpone visits to service centres where possible and complete transactions online.
Authorities in Australia’s Northern Territory also reported interruptions affecting government services.
Some hospitals and healthcare institutions experienced administrative difficulties, although medical representatives stressed that the disruptions were not affecting direct patient care.
The President of the Australian Medical Association, Michael Bonning, explained that the affected Microsoft systems were not used for direct clinical treatment.
“We don’t use any of these things for direct patient care… We’ve always got workarounds for that,” Bonning said.
He disclosed that some healthcare facilities had temporarily returned to paper-based processes for issuing prescriptions.
Australia’s Minister for Home Affairs and Cybersecurity, Tony Burke, also commented on the disruption after speaking with Microsoft representatives in the country.
Burke said the company did not believe the outage was connected to a cyberattack.
According to him, Microsoft officials “do not believe they are dealing with a cyber event”.
He explained that the disruption appeared to resemble circumstances surrounding the July 2024 CrowdStrike incident, when a faulty software update caused widespread problems for computers running Microsoft Windows.
“They believe that they’re dealing in some ways similar to what we saw with respect to CrowdStrike, where there is an update that has gone awry,” Burke told reporters.
The minister stressed that the immediate impact of the latest disruption was particularly noticeable in email services.
“One of the things that we had with CrowdStrike was we then had a whole lot of downstream impacts where it was affected the capability of a whole range of other products,” he explained.
In July 2024, millions of people worldwide experienced technological disruptions after American cybersecurity company CrowdStrike released a faulty software update that caused Windows-operated computers to malfunction.
However, Microsoft has not established that the latest outage was caused by the same type of failure.
Cybersecurity experts have warned that the disruption could have consequences extending far beyond individuals being unable to access their emails.
Australian cybersecurity expert Troy Hunt said the outage demonstrated the central role Microsoft’s infrastructure plays in modern digital communication and business operations.
“Microsoft is a massive part of the internet backbone and reminds us how critical email still is,” Hunt stated.
He explained that the consequences extended to activities requiring email verification, including purchases, appointments, account creation and access to online services.
“Not only does this outage affect many people’s ability to work but also things like the ability to communicate about appointments, purchase things that need verification, create or access accounts and services,” he said.
Hunt stressed that the development highlighted the importance of contingency plans and alternative systems for businesses that rely on cloud-based services.
Another technology expert, Paul Spain of New Zealand-based advisory firm Gorilla Technology, expressed concern about the scale of the disruption and its potential economic consequences.
Spain argued that if the incident was not caused by a cyberattack, the failure reflected serious shortcomings in the operation of the affected systems.
He described the situation as “incredible incompetence” and warned that a prolonged outage could result in millions of dollars in economic losses.
According to him, businesses dependent on Microsoft’s email and productivity applications had effectively “lost a business day”.
The disruption has also generated widespread reactions on social media, where affected users have shared jokes and complaints about their inability to work.
One widely circulated post referred to the 2002 music video for Dilemma by Nelly and Kelly Rowland, in which Rowland is seen typing a message into a spreadsheet.
“With Outlook down, it’s time to be like Kelly Rowland and start sending emails through Excel,” a social media user joked.
The post reportedly attracted about 23,000 likes and nearly 3,000 shares.
An American real estate company, Surmont, also commented on the outage, writing on Instagram:
“Days like today remind you that your entire job is just sending emails.”
Another user jokingly questioned whether the continued disruption entitled workers to abandon their duties for the remainder of the week.
“If Outlook doesn’t come back we are legally allowed to take the rest of the week off?” the user wrote.
Despite the humour, the situation has caused serious disruption to businesses and organisations that depend on reliable access to email, calendars and digital collaboration tools.
Microsoft has continued efforts to restore the affected services, but its latest update indicates that technical solutions introduced so far have not achieved the anticipated results.
The company is now testing other recovery measures while monitoring the ability of its infrastructure to accommodate returning users.
Although the number of reported service failures has declined from the earlier peak, the outage remains unresolved in the latest information provided.
