Microsoft Shares Slide Nearly 3% In Friday Pre-Market Trading After Global Outage Hits Key 365 Services

Microsoft Corporation Common Stock (MSFT) shares came under pressure on Friday, 13 November 2026, after a prolonged global outage affected its productivity and communication services. Outlook, Teams and its artificial intelligence (AI) assistant Copilot were among the affected platforms.

The disruption lasted more than 12 hours, leaving users unable to access essential services. Microsoft outage reports emerged from more than 70 countries and territories.

Microsoft shares (or MSFT shares) fell about 2.8% in pre-market trade on Friday. The dip was a sign of concerns about the interruption and the possible effect on the company's enterprise software segment.

This was a pre-market indication, not the regular-session closing price. For the session, the MSFT share price closed at $523.88, up 0.17% on the Nasdaq.

Why Did The Microsoft 365 Outage Occur?

Microsoft said its engineers had identified elevated server loads and infrastructure issues as likely contributors to the connectivity problems. Several servers had unexpectedly become unavailable after failing automated health checks. This placed additional traffic on the remaining infrastructure and contributed to connection errors.

The company also said its initial recovery measures had not delivered the expected improvement. It was evaluating alternative ways to increase capacity amid persistent traffic-management imbalances.

What Did Microsoft Do To Restore Services?

Microsoft later reported signs of stabilisation following broader fixes. However, it continued to prioritise a complete and sustained recovery. The company also said it was not aware of any malicious activity or cyberattack behind the Microsoft 365 outage.

The company said the outage affected several Microsoft 365 offerings connected to Exchange Online and email services. It was investigating the issue and exploring different ways to bring affected servers back online.

Did The Microsoft Outage Shake Investor Confidence?

The outage exposed just how much businesses and institutions rely on Microsoft’s software ecosystem for everyday communication and operations. Government agencies in Australia, Japan, and the US reported disruptions. In India, airlines, including IndiGo, Akasa Air, and Air India, reported that their email support services were affected.

The company has also faced other service interruptions this year, including an Azure cloud outage in the previous month.

The immediate financial impact of the latest incident remained unclear. But frequent disruptions could prompt enterprise customers to rethink their reliance on Microsoft’s platforms. That worry becomes increasingly crucial as the company launches more AI-powered productivity services.
