The company, in a statement, apologised for the disruptions caused to customers and partners, and ruled out any cyberattack.
Microsoft's executive vice president for Copilot, agent and platform, Charles Lamanna, said the company was “reviewing what happened and how we can prevent similar issues going forward.” Sharing an update on the outage which disrupted Outlook, Teams and other Microsoft 365 services on Friday, Lamanna said the company was seeing “encouraging recovery progress”, adding that service availability and email delivery performance had improved across a growing portion of affected infrastructure.
Following the disruption, at least 43,000 users across 72 countries had reported problems accessing Outlook within an hour, according to outage-tracking website Downdetector, with complaints rising across several European countries as users began their day.
The disruption, which began on Thursday, has affected email access, calendar functions and workplace communication, with several businesses and government agencies reporting operational problems. Microsoft is continuing to test fixes, redistribute traffic and increase server capacity as it works to stabilise its infrastructure.
The outage raised concerns about the widespread dependence on Microsoft's cloud-based ecosystem, with disruptions to a single infrastructure provider having consequences for businesses and users worldwide.
Key points on the Microsoft outage:
Outlook and Teams disrupted: Users reported problems accessing emails, sending messages, signing in and using certain Teams features.
Outage spreads to Asia-Pacific: India, Australia and Japan reported disruptions as the outage spilled into Friday's business hours.
Microsoft struggles to restore services: The company reported partial recovery in some regions, but server adjustments have not resulted in sustained restoration.
Businesses and agencies affected: Indian airlines IndiGo and Akasa Air reported email support disruptions. Government agencies in Australia, Japan and the US were also impacted.
No cyberattack suspected: Microsoft said it was not aware of malicious activity causing the outage. Australia's cyber security minister said Microsoft believed the issue was not a cyberattack.
