A massive Microsoft outage disrupted business operations across 74 countries and territories, leaving employees unable to access essential workplace tools as problems with Outlook, Teams and Microsoft 365 stretched from Thursday into Friday.
The disruption affected corporate communications, online meetings, email access and cloud-based collaboration services, creating difficulties for businesses, government agencies and employees dependent on Microsoft’s software.
Outage monitoring service Downdetector reported that complaints spread to 74 countries and territories within approximately one hour of the disruption beginning Thursday. The affected regions included North America, Europe, Asia and parts of Africa.
The disruption was particularly severe for Outlook, Microsoft’s widely used email service. Nearly 140,000 global problem reports were recorded around 1800 GMT Thursday, according to Downdetector data cited by news organizations. The number represents submitted reports, not a confirmed count of affected users.
Reuters reported more than 97,000 Outlook complaints in the United States at 2:07 p.m. Eastern Time, alongside more than 38,000 Microsoft 365 reports and approximately 4,500 Teams complaints.
The actual number of affected users could be considerably higher, although Microsoft has not published a comprehensive figure.
Microsoft Says Recovery Attempts Have Failed to Deliver Expected Results
Microsoft attributed the disruption to infrastructure problems that reduced available server capacity and placed additional pressure on functioning systems.
The company initially attempted to restore services by restarting affected servers, pausing software deployments and redirecting traffic away from overloaded infrastructure.
However, some recovered servers became unresponsive again when traffic returned, complicating restoration efforts.
“We’re aggressively pursuing all pathways to reduce impact,” Microsoft said during its response to the outage.
In a subsequent update, the company acknowledged that its recovery measures were not producing the anticipated results.
Microsoft said engineers were examining alternative methods to increase capacity and restore connections without overwhelming the remaining infrastructure.
The company also indicated there was no evidence of a cyberattack behind the disruption.
Global Workplaces Disrupted as Outage Spreads to Asia
The outage extended beyond Microsoft’s traditional email and messaging services, affecting SharePoint, OneDrive, Copilot and connections used by other technology companies.
OpenAI and Anthropic reported problems involving their Microsoft 365 connectors, illustrating how failures within one major cloud ecosystem can affect services operated by other companies.
The disruption also reached government systems. Officials in Japan reported problems affecting government IT infrastructure, while authorities in Western Australia said Microsoft was prioritizing critical government and safety-related services.
Singapore users were among those affected, according to Channel NewsAsia, as the disruption continued into Asian business hours Friday.
For employees relying on Teams for meetings, Outlook for business correspondence and SharePoint for document access, the disruption interrupted routine work and delayed communications.
However, the phrase “employees go jobless” would be misleading. There is no evidence that workers lost their jobs because of the outage. The verified impact concerns temporary interruptions to workplace systems rather than employment losses.
The incident highlights the risks of businesses depending heavily on a single technology provider for multiple critical functions.
When email, messaging, document sharing and AI integrations rely on interconnected infrastructure, a server failure can disrupt several workflows simultaneously.
As of Friday morning, Microsoft was continuing restoration efforts, with some services recovering gradually while others remained affected.
The company had not announced a confirmed time for full restoration.
