Global Microsoft outage disrupts email, government systems, and event access

Millions of Microsoft customers worldwide face ongoing disruption after a major technical failure hit key services including Outlook, Teams, and Copilot starting around 6pm on Thursday.

What Happened

Microsoft stated the outage likely stemmed from server settings used for Microsoft 365, though the company ruled out a cyber attack. The technical failure impacted government agencies in the United States, Australia, and Japan, alongside AI firms OpenAI and Anthropic, and European stock market operator Euronext, which advised listed companies to use telephones for corporate communications due to email failures. In the UK, GMB national secretary Rachel Harrison reported that GMB union data showed ambulance services and NHS 111 and 999 trusts experienced email backlogs, while Sir Ciarán Devane, chief executive of the NHS Alliance, confirmed that core clinical and operational systems remained functional. In sport, Cheltenham urged racegoers to arrive early to handle potential issues with digital tickets purchased through Microsoft-associated accounts.

Recovery

Microsoft applied a software patch and reported positive results for server stability, noting incremental improvements across affected infrastructure. Despite these recovery efforts, the company stated that service health remains variable and capacity has not yet fully returned to baseline for Microsoft 365 Business, Enterprise, and consumer products.

Context

Cloud-based productivity suites like Microsoft 365 serve as central digital infrastructure for businesses, healthcare providers, and government agencies around the globe. When core authentication or server settings fail, the resulting downtime rapidly affects routine communications and administrative workflows across multiple industries simultaneously.
