Microsoft 365 Global Outage – Outlook, Teams and Copilot Affected Worldwide
Microsoft users across several countries faced disruptions to Microsoft 365 services, including Outlook, Microsoft Teams and Copilot, following a major service outage reported on November 12 and November 13, 2026.
The disruption affected access to email and several workplace applications, creating difficulties for businesses, educational institutions and professionals who depend on Microsoft’s cloud services.
According to reports, outage complaints came from dozens of countries and territories. Microsoft acknowledged the service problems and said it was working to restore normal operations.
Which Microsoft services were affected?
The reported disruption involved several Microsoft 365 products and connected services.
The affected services included:
- Outlook: Users reported problems accessing mailboxes and sending or receiving emails.
- Microsoft Teams: Some users experienced issues with workplace communication and related features.
- Microsoft Copilot: Users reported difficulties accessing the AI assistant and receiving responses.
- SharePoint and other services: Certain features that depend on Exchange Online were also affected.
The extent of disruption differed between services. Not every feature or user was necessarily affected in the same way.
What caused the Microsoft outage?
Microsoft initially reported elevated infrastructure load affecting Exchange Online connectivity.
Reports also indicated that some restarted servers became unresponsive again after traffic returned. Microsoft said its initial corrective changes had not worked as expected and that it was exploring further recovery measures.
This points to an infrastructure and service availability issue rather than a problem caused by individual users’ devices.
Microsoft had not provided a definitive public explanation of every technical factor behind the disruption in the reports available at the time of publication.
How did the outage affect businesses?
Many organisations use Microsoft 365 for daily operations, including email communication, meetings, document sharing and project coordination.
An outage involving these services can affect:
- Business email communication.
- Online meetings and scheduling.
- Internal team collaboration.
- Access to certain cloud-based workflows.
- AI-assisted workplace productivity.
Organisations that rely on a single cloud platform may face delays when important services become unavailable.
The incident highlights the importance of business continuity plans and alternative communication methods.
What should Microsoft users do?
Users experiencing problems should first check Microsoft’s official service health information.
Recommended steps include:
- Check the Microsoft service status page.
- Avoid repeatedly reinstalling applications.
- Try accessing the service again after Microsoft’s recovery updates.
- Use an alternative communication channel for urgent work.
- Avoid clicking unexpected links in emails or messages claiming to offer outage fixes.
- Do not share passwords or verification codes with anyone offering unofficial support.
Repeatedly changing account settings or deleting applications is unlikely to resolve a wider server-side outage.
Is Microsoft 365 working again?
Service availability can change while Microsoft works on recovery. Microsoft’s service status page should be treated as the latest source for whether individual products are operational.
Users should not assume that all services have recovered simply because one application starts working.
