A Microsoft outage on Thursday, 12 November 2026, left thousands of users unable to use Outlook, Teams, Copilot and other Microsoft 365 services. Microsoft says several of its servers suddenly became unavailable, which put extra strain on other systems. Recovery has been gradual and, in the latest updates we checked on 13 November 2026, was still not complete.

Join NowWhich Microsoft Services Were Affected?
Outlook email was the most visible casualty. Microsoft also listed Exchange Online, Teams, SharePoint Online, Copilot 365, Defender XDR, Planner, To Do and Intune among the services that could be affected.
Some workplace tools that connect to Microsoft accounts also had trouble. OpenAI and Anthropic both reported problems with their Microsoft connectors, so linked AI tools may not have worked as expected. Users in India were among those reporting email access issues.

What Caused the Microsoft Outage?
Microsoft first pointed to “elevated load” on its infrastructure across multiple regions. It later clarified that the pressure did not come from a jump in traffic. Instead, a number of servers unexpectedly stopped responding, and that put strain on the rest of the system.
Microsoft says it has found no sign of malicious activity. ✅ That part is confirmed by the company. The deeper root cause has not been explained, and Microsoft had not said whether a recent change triggered it.
How Recovery Has Gone So Far
Recovery has not been a clean switch-back. Microsoft restarted affected infrastructure, moved traffic across its worldwide systems and returned servers to service in stages. Some restored servers worked at first, then became unresponsive again once traffic reached them.
Microsoft then said it was applying its fix more broadly and preparing automated tools that detect and restart unresponsive servers. The company warned that users could see a gradual recovery as their apps reconnect.
By Thursday evening in the US, Outlook problem reports had fallen to roughly 34,000 from the peak, which suggests improvement, not a full fix.
Impact Beyond Email
The disruption reached business operations. Electric truck maker Workhorse Group postponed its third-quarter results announcement from 12 November to 16 November, citing disruption caused by the outage. For companies that run mail, meetings and security tools on Microsoft 365, a multi-hour failure can stall a working day.
What This Means for Users
- If you use Outlook or Teams personally: the fault is on Microsoft’s side, so resetting passwords or reinstalling apps is unlikely to help. Wait and try again after some time.
- If you manage Microsoft 365 for a company: follow the Service health page in the Microsoft 365 admin center for updates specific to your organisation. Avoid big configuration changes while the incident is active.
- If you have an urgent email or meeting: ⚠️ keep a backup channel such as a phone call or another messaging app until services look stable.
- If your emails seem delayed: messages may arrive late as servers catch up, so check again before resending.
Frequently Asked Questions
Is Microsoft down right now?
Microsoft was still restoring service in the latest updates we checked on 13 November 2026, with limited recovery reported. Your own experience may vary by region and account. Admins should check their Service health dashboard for the status of their organisation.
Was the Microsoft outage a cyber-attack?
Microsoft has said there is no indication of malicious activity. It attributed the disruption to servers becoming unexpectedly unavailable under heavy load, not to an attack or a surge in traffic.
Why is Copilot not working?
Copilot 365 is one of the services Microsoft listed as affected, so it relies on the same troubled infrastructure. It should come back as capacity is restored. Third-party AI tools that connect to Microsoft accounts may also have had problems.
Do I need to do anything to fix Outlook or Teams?
Not usually. This is a server-side problem, so there is nothing to repair on your device. Microsoft says apps will reconnect gradually as capacity returns, so waiting and retrying later is the safest approach.
Final Word on the Microsoft Outage
The outage shows how much daily work depends on a few cloud services. Watch for Microsoft’s own post-incident explanation, which should clarify what actually made the servers fail.
