“Microsoft” said Friday that a widespread outage affecting its services was caused by a technical issue, not cyber activity, artificial intelligence or AI agents. The company apologized to customers and partners as recovery efforts continued, according to Anadolu Agency.

“This was a technical issue not related to cyber or AI / agents,” the company said in a statement.

“Microsoft” traced the disruption to an underlying problem introduced during an earlier network capacity upgrade. It emerged after a recent network change.

The company said the issue had been resolved and services were broadly recovering and stable. Restoration efforts were still under way for remaining customers and regions.

“We are deeply sorry for the disruption this incident has caused our customers and partners,” “Microsoft” said. “We know the trust they place in our services and take that responsibility extremely seriously.”

“Microsoft” said it restored services gradually because of the scale of demand, checking stability at each stage. “While this took longer, it helped ensure a stable restoration,” it said.

The company pledged to publish a full post-incident report after its investigation is complete.

The outage began Thursday with Exchange Online, which powers business email through “Outlook”, and continued into Friday. It also disrupted features in other “Microsoft 365” services that rely on Exchange Online, including “Teams” calendars, “Copilot” and “SharePoint”.

The disruption affected communications at businesses, schools and government agencies. Some users continued to face access problems and email delays as services recovered.
