After a nearly 24-hour lapse in service, Microsoft provided a partial explanation for the outage that took down popular business email accounts in 74 countries.
In a statement, the company said the outage was not related to Cyberattacks or AI agents but stemmed from a “technical issue.”
The company said it would provide a more detailed explanation once it completed a full report on the incident.
“The incident was introduced by an issue during an earlier network capacity upgrade that surfaced following a recent network change. We have addressed the underlying issue and continue to restore service to remaining customers and regions,” the company said.
We are deeply sorry for the disruption this incident has caused our customers and partners. We know the trust they place in our services and take that responsibility extremely seriously. We are seeing broad recovery and stability across our services.
