Microsoft outage spills into Asia-Pacific business hours despite partial recovery
MSFT•Microsoft said server adjustments brought partial recovery but not sustained service restoration after an outage affecting Outlook, Teams and Copilot spread into Asia-Pacific business hours. Downdetector showed more than 18,000 US Outlook problem reports late Thursday, after a peak of more than 130,000.
1. Partial recovery
A disruption to Microsoft services including Outlook, Teams and Copilot stretched into Asia-Pacific business hours on Friday after affecting thousands of US users. Microsoft said it had adjusted affected servers and observed some partial recovery, but the changes had not produced sustained restoration.
2. Email services affected
Microsoft said Microsoft 365 features relying on Exchange Online and email were affected, while elements not dependent on Exchange Online remained functional. The company said it was not aware of malicious activity causing the outage. Downdetector showed more than 18,000 US reports of Outlook problems at 11:30 p.m. ET Thursday, following a peak above 130,000 around 1 p.m.
3. Regional business impact
Government agencies in Australia, Japan and the United States were affected, as were OpenAI and Anthropic. IndiGo and Akasa Air said their email support services were impacted, and a Taiwanese securities firm cancelled a scheduled bond repurchase transaction. Microsoft had also experienced outages involving its 365 services in January and October of the previous year.
