Microsoft meltdown: Caused by AI? A cyber attack? Your questions answered
Microsoft services including Outlook, Teams, Copilot and parts of its cloud platform suffered widespread disruption, affecting customers around the world. The outage matters because Microsoft 365 services used by hundreds of millions rely on Exchange Online for email and related functions, and some users were left unable to access them.
Microsoft said the incident began at 4.17pm UK time and involved server failures, elevated infrastructure load and an imbalance in traffic within Exchange Online. Downdetector recorded nearly 140,000 Outlook problem reports by 6pm, while reports across five services peaked at 19,650 a minute; Microsoft said there was no indication of a cyber attack, and AI services appeared to be affected as a consequence rather than causing the outage.
In short
- Outlook reports reached nearly 140,000.
- Exchange Online server problems disrupted several Microsoft services.
- Microsoft said there was no indication of a cyber attack.
Explained simply
Microsoft provides online services used by people and organisations for email, meetings, cloud computing and AI tools. Outlook and Teams are part of Microsoft 365, while Exchange Online handles email and related functions behind the scenes.
These services depend on large networks of servers and connections that must manage demand and route traffic. If part of that infrastructure fails or becomes overloaded, users may lose access even when the problem is not with their own devices.
The disruption affected customers in several countries and touched services that many workplaces rely on each day. Understanding whether it stemmed from technical failures, a cyber attack or another cause matters for assessing the risks to those services.
