Original title: Microsoft 365 Crawls Back to Life After a 24-Hour Outage
Microsoft blames a network capacity upgrade, not cyber or AI, and extended email queue time to 48 hours.
Microsoft 365 services for businesses, governments, and other users went down starting around noon Eastern on Thursday and spread beyond an initial North America impact to more than 70 countries. Outlook, Teams, Copilot, and related services are mostly back, according to Microsoft. The company says the failure followed a network change during an earlier capacity upgrade and has promised a full post-incident report.
Unconfirmed: Microsoft has not published the full root-cause review; it says the outage was not a cyberattack or caused by AI.
- Downdetector reports began just after 12 pm ET.
