Microsoft confirms global outage resolved, rules out cyberattack
Microsoft attributed the outage to a network capacity upgrade issue, confirming that the disruption was unrelated to cyberattacks or AI agents.
Microsoft said it had restored Microsoft 365 services after a global outage disrupted Outlook, Teams and other applications for more than 24 hours, reiterating that the disruption was not caused by a cyberattack.
On Saturday, the company said it had “restored service to the remaining impacted customers and regions,” directing customers to incident MO1550821 in the Microsoft 365 admin center.
On Friday, Microsoft said that the outage stemmed from a problem introduced during an earlier network capacity upgrade that emerged after a recent network change. “This was a technical issue not related to cyber or AI/agents,” the company said.
