New Delhi, November 13, 2026: Microsoft is facing a major global service disruption that has affected several of its widely used platforms, including Outlook, Microsoft Teams, Microsoft 365 and its AI assistant Copilot. The outage, which began on Thursday, November 12, continued into Friday, leaving users and businesses in multiple countries struggling to access essential digital services.
The disruption has affected both individual users and organisations that depend on Microsoft's cloud-based infrastructure for daily operations. Reports of technical problems emerged across 74 countries and territories within approximately an hour, highlighting the widespread impact of the incident.
Outlook Users Face Email Access Problems
Outlook has been among the most affected services during the disruption. Users reported difficulties accessing their inboxes, sending emails and receiving incoming messages through both desktop and web applications.
Microsoft warned that email delivery could be delayed and that some users might temporarily lose access to their mailboxes.
The disruption has created difficulties for businesses that rely heavily on email communication for customer support, internal coordination and important transactions.
Microsoft Teams and Copilot Also Experience Disruptions
Microsoft Teams users also experienced problems, particularly with calendar-related features, including scheduling and viewing meetings.
However, Microsoft indicated that several core Teams functions, such as joining calls, participating in meetings, group chats and channel messages, remained largely operational.
The company's AI assistant, Copilot, was also affected. Some users faced difficulties loading Copilot Chat or receiving responses. Features that depend on workplace information, including emails, calendars and documents, were also disrupted.
What Caused the Microsoft Outage?
Microsoft said the disruption was linked to unexpected server unavailability rather than an unusual increase in user traffic.
According to the company's updates, several servers became unexpectedly unavailable, increasing the workload on the remaining infrastructure and creating additional pressure on its systems.
Microsoft has been investigating the underlying technical issue and working on multiple recovery measures, including restoring affected backend servers and redirecting traffic.
The company also indicated that a recent network configuration change was being rolled back as part of its recovery efforts. However, the exact root cause had not yet been officially confirmed.
Was Microsoft Hit by a Cyberattack?
The global outage raised concerns among users about a possible cyberattack.
However, Microsoft stated that it was not aware of any malicious activity responsible for the incident. The company said it would share further details through a post-incident report after the disruption was brought under control.
Impact on India: IndiGo's Email Support Affected
India was among the countries reporting problems with Microsoft's services.
Indian users began reporting difficulties late Thursday night, with another increase in outage complaints on Friday morning.
The disruption also affected businesses. Airline IndiGo announced that its email support services had been impacted and that it might not be able to receive customer emails.
The airline advised customers requiring urgent assistance to use its website or mobile application and contact its virtual assistant, 6E Skai. Other support channels remained available.
Microsoft Begins Recovery Efforts
Microsoft has been working to restore its affected services and improve system capacity. However, its recovery efforts faced challenges as some servers reportedly became unresponsive again after receiving traffic.
The company continued monitoring its infrastructure and exploring alternative technical solutions to stabilise services.
Users were advised to monitor official Microsoft service-status updates for information about restoration.
