Microsoft Outage Disrupts Global Services

What Happened

On Thursday, November 13, 2026, Microsoft services began experiencing disruptions globally, with users reporting issues with Outlook, Teams, and other Microsoft 365 applications.

The outage, which was caused by a technical problem with Microsoft's server infrastructure, has affected over 430 million users worldwide, including businesses, governments, and individuals.

According to Microsoft, the issue was not caused by a cybersecurity breach, but rather by an elevated load on its infrastructure, which led to a large number of servers becoming unexpectedly unavailable.

What the Evidence Establishes

Experts have noted that the incident is taking longer to resolve than expected, considering Microsoft's stature and engineering expertise.

Where the Accounts Conflict
