A major global service disruption affecting Microsoft’s cloud ecosystem has impacted businesses and individuals worldwide, highlighting how heavily modern organizations depend on cloud-based communication and productivity platforms.
On November 12–13, 2026, Microsoft experienced a widespread outage affecting several Microsoft 365 services, including Outlook, Microsoft Teams, and Copilot. Users across multiple countries reported difficulties accessing email, sending and receiving messages, and using essential workplace collaboration tools.
The incident demonstrated how a disruption in a major technology platform can affect everyday business operations, communication, and productivity.
What Happened During the Microsoft Global Outage?
Microsoft reported service disruptions affecting its Microsoft 365 infrastructure, particularly services dependent on Exchange Online.
The reported issues included:
- Microsoft Outlook: Users experienced difficulties accessing mailboxes and sending or receiving emails.
- Microsoft Teams: Some users experienced connectivity and collaboration issues.
- Microsoft Copilot: Users reported interruptions in AI-powered services.
- Microsoft 365 Services: Other connected business services also experienced disruptions.
According to reports, the outage affected users across 74 countries and territories. Microsoft identified infrastructure instability and elevated server loads as contributing factors while working to restore services.
Microsoft also stated that it had no indication that the incident was caused by malicious or cyber activity.
At the time of writing, Microsoft was continuing its recovery efforts and monitoring service stability.
How Did the Outage Affect Businesses?
For organizations that rely on Microsoft 365, even a temporary interruption can create significant operational challenges.
Email is one of the most important communication channels for modern businesses. When Outlook becomes unavailable, organizations may experience:
- Delays in customer enquiries and responses.
- Interruptions in internal communication.
- Delayed quotations, invoices, and business correspondence.
- Difficulties coordinating meetings and daily operations.
- Reduced productivity for employees working remotely or across multiple locations.
Such incidents remind businesses that even reliable cloud platforms can experience unexpected service disruptions.

During this Microsoft global outage, Habre Nepal proactively communicated with customers to inform them about the ongoing disruption and its potential impact on Microsoft services.
Our priority was to ensure that customers were aware of the situation, understood that the issue was related to Microsoft’s global infrastructure, and knew that the disruption was not necessarily related to their individual systems or configurations.
Our approach focused on three important areas:
- Timely Customer Communication: We communicated with customers regarding the Microsoft service disruption, helping them understand why they might be experiencing difficulties accessing their Microsoft 365 services.

What Should Microsoft 365 Users Do During a Global Outage?
When a major cloud service provider experiences an outage, users should avoid unnecessary troubleshooting that could create additional problems.
Here are some practical recommendations:
- Check Microsoft’s Service Health: Visit the official Microsoft 365 service health dashboard for updates.
- Avoid Unnecessary Configuration Changes: Do not randomly modify email settings, DNS records, or Microsoft 365 configurations during a confirmed provider-side outage.
- Use Alternative Communication Channels: For urgent business matters, use available communication methods such as telephone or other messaging platforms.
- Keep Customers and Employees Informed: Communicate possible delays and provide alternative contact methods where necessary.
- Monitor Service Restoration: Wait for Microsoft’s official recovery updates and verify that services are functioning normally before resuming critical activities.
