Microsoft struggled to restore its services on Friday after a major outage disrupted Outlook, Teams and Copilot across the United States and Asia-Pacific region.

The disruption affected government agencies in the U.S., Australia and Japan, as well as businesses including OpenAI and Anthropic. The outage lasted around 12 hours, with more than 130,000 reports of Outlook problems recorded in the U.S. at its peak, according to Downdetector.

Microsoft said it had made changes to affected servers but had not achieved a full recovery.

“We're reviewing what additional actions we can take to improve overall infrastructure stability,” the company said on X.

Government agencies and businesses affected

The disruption hit email services in several countries. Australia's intelligence agency and federal police were among those affected.

Australian Home Affairs and Cyber Security Minister Tony Burke said Microsoft did not believe the incident was caused by a cyberattack.

He compared the situation to the 2024 CrowdStrike outage, suggesting a faulty software update could be involved.

“The impact that they are dealing with ... is very much on email systems,” Burke said.

Japanese government systems were also affected, while the U.S. House of Representatives confirmed that its users had experienced problems.

Growing concerns over reliability

Businesses also reported difficulties. OpenAI and Anthropic experienced issues with Microsoft connectors, while Indian airlines IndiGo and Akasa Air reported disruptions to their email support services.

The latest incident adds to concerns about Microsoft's service reliability. The company experienced another Microsoft 365 outage in January and a wider Azure disruption last month.

Market analyst Josh Gilbert warned that repeated failures could eventually affect customer confidence.

“If reliability starts to look like a recurring problem, it hands every IT department a reason to think twice before putting even more of their business in one provider's hands,” he said.

Microsoft said it was continuing to investigate the problem and work towards restoring normal service.
