New Delhi, November 2026 : US-based technology major Microsoft has restored its services following a worldwide disruption that affected Outlook, Teams and several other Microsoft 365 applications used by businesses and individuals for more than a day.
The company updated its service status page on Saturday to indicate that all products were operational, bringing an end to an outage that had disrupted access to email, virtual meetings and cloud-based workplace tools across multiple countries since Thursday.
Microsoft said the disruption originated from a technical issue linked to an earlier network capacity upgrade, which was exposed following a subsequent network change. The company clarified that the incident was neither related to cyber threats nor caused by its artificial intelligence systems.
"We are deeply sorry for the disruption this incident has caused our customers and partners," Microsoft said in a post on social media platform X, adding that it takes customers' trust in its services extremely seriously.
The outage primarily affected Exchange Online, Microsoft's cloud-based email platform, with disruptions extending to dependent services such as Outlook, Teams, Microsoft 365 Copilot, SharePoint Online and Microsoft Defender XDR.
Users reported difficulties accessing emails and calendars, scheduling meetings and retrieving information through Copilot. The disruption affected businesses and consumers relying on Microsoft's cloud-based applications for communication and daily operations.
Microsoft's understanding of the technical problem evolved during its investigation. The company initially attributed the disruption to elevated infrastructure load across several regions. It later identified that some servers had unexpectedly become unavailable, increasing the workload on the remaining infrastructure.
The company subsequently clarified that unusually high user traffic was not responsible for the outage.
Restoration efforts also encountered difficulties when some servers that had recovered became unresponsive after traffic was redirected to them. Engineers responded by modifying traffic management processes and gradually restoring system capacity.
Microsoft said services were brought back in phases, with engineers monitoring system performance and stability to prevent further disruptions.
The outage also affected airline operations. Several airlines reported on Thursday that their email-based customer support channels had been disrupted, although alternative support channels continued to remain available.
The incident once again highlighted the dependence of businesses and essential service providers on cloud-based platforms and the importance of maintaining reliable digital infrastructure.
