Microsoft attributed the outage to a network capacity upgrade issue, confirming that the disruption was unrelated to cyberattacks or AI agents. The company stated that it 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 (1). [1]
On Saturday, the company said it '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 (1). [1]
The company said it addressed the underlying issue and restored services gradually, checking stability before proceeding to the next stage. Microsoft apologized for the disruption and said it would publish a full post-incident report once its review is complete (1). [1]
The outage began Thursday, disrupting access to Exchange Online mailboxes and features linked to Outlook, Teams, and Microsoft Copilot. Government agencies in Japan, Singapore, and the United States experienced email problems, while connections between Microsoft 365 and AI assistants were also affected (1). [1]
