Microsoft 365 services recover after nearly two-day global outage
Microsoft Outlook and Microsoft 365 services are recovering after an outage lasting almost two days and affecting millions of users worldwide. Microsoft said on Friday that it was seeing broad recovery and stability, while some users still faced degraded features or delayed email; the disruption also affected SharePoint, Teams, Copilot and other 365 apps.
Microsoft traced the incident to a problem during an earlier network capacity upgrade that surfaced after a later network change. It said the outage was not related to cyber activity or AI agents, and that services were restored gradually to check stability across regions. The company said it would publish a full post-incident report after its review.
In short
- Outlook and Microsoft 365 began recovering after nearly two days.
- The outage affected millions and disrupted several Microsoft services.
- Microsoft linked it to network changes and ruled out cyber and AI causes.
Explained simply
Microsoft 365 is a group of online work tools run by Microsoft, including Outlook for email, Teams for meetings and chat, and SharePoint for sharing files. Many organisations and individuals rely on these services to communicate and work.
The services run across networks and data centres in different regions, so a technical fault can affect users in many countries at once. An outage can interrupt email, meetings and access to shared documents, with effects depending on which features are affected and how quickly they recover.
Microsoft operates the services and investigates faults in its systems. Its review of what happened can help explain how the network changes contributed to the disruption and what steps may reduce the chance of a similar outage.
