SEATTLE - Microsoft is speaking out one day after a widespread outage, which left thousands of users unable to access email and cloud tools. 

Microsoft apologizes after widespread outage

What they're saying:

Microsoft said the disruption involved an "elevated system load" after several servers went offline, overwhelming the remaining infrastructure.

"We are deeply sorry for the disruption this incident has caused our customers and partners," Microsoft said in a statement on Friday. "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." 

The tech company said the outage was related to a technical issue and not related to cyber security or artificial intelligence. 

"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," Microsoft continued. 

The company said "given the scale of demand," they restored services gradually, validating stability at each stage. 

"While this took longer, it helped ensure a stable restoration," they explained. 

Microsoft said it will provide a full post-incident report once its review is complete.

The backstory:

Earlier Friday, Microsoft reported improvements in mailbox access and the processing of delayed emails in North America. However, Outlook, Copilot and other workplace tools remained disrupted, with some users still experiencing intermittent issues.

The company also extended the delivery window for delayed messages, giving emails caught in the backlog until at least Saturday afternoon to reach recipients before being marked undeliverable.

The widespread outage began Thursday. During earlier recovery attempts, some servers initially appeared healthy after returning to service but became unresponsive again once they began receiving traffic.
