Microsoft has confirmed that it has fully restored its services after a global outage that began on Thursday which lasted more than 24 hours.

According to Microsoft, Outlook, Teams and the Copilot AI assistant were among the products reported down, emphasizing that they have completed efforts to address the underlying issue of the incident and restored service to the remaining impacted customers and regions.

The company said the cause was a technical problem, not a cyberattack or AI-related activity as well as Microsoft’s failure to trace an issue during a network capacity upgrade.

Microsoft first said it was investigating reports in the Americas, but later confirmed that Microsoft 365 connectivity was affected for users in any region.

The outage hit government agencies in Australia, Japan and the US, along with healthcare services, schools and companies.

The system outage also impacted corporate earnings according to reports gathered.

According to varying reports, it was reported that at its peak, more than 130,000 reports of Outlook problems came in from US users.

According to the statement released by Microsoft, it recovery session will come in stages, noting that consumer services had recovered by Friday afternoon, while enterprise services were still being monitored for delayed email.

The company said it restored capacity gradually because of the scale of demand, checking stability at each step. It has promised a detailed post-incident review once its investigation is complete.

The outage is the second major disruption to Microsoft 365 this year, after one in January.

Rob Demain, chief executive of cybersecurity firm e2e-assure, said it was a stark reminder of how heavily the world relies on a handful of big tech providers.
