Microsoft says it has fully restored its services after a day-long global outage that disrupted businesses, government offices and other services across many countries.
On Saturday morning the firm announced that it had finished fixing the underlying problem and had brought service back for the remaining customers in every affected region. The outage hit Outlook, Teams and the Copilot AI assistant, and has been called among the most serious IT failures seen for several years.
What caused it
Microsoft attributed the disruption to a problem linked to a network capacity upgrade. It said the incident had nothing to do with a cyberattack and was not caused by AI agents, a possibility some users had raised while services were down.
Who was affected
Because so many organisations rely on Microsoft 365 for email, meetings and shared documents, the effects spread quickly. Government offices, companies and public services in several countries reported trouble reaching their tools. For many workers, the day meant missed messages, interrupted video calls and delayed work.
Why a single fault can reach so far
Cloud services concentrate a huge number of customers on shared systems. That makes them efficient, but it also means that a change to the network behind them can affect people everywhere at once. This outage is a reminder that routine upgrades, not just attacks, are a common source of large failures.
What users should do now
Most people should find that their accounts work normally again. If something still looks wrong, signing out and back in, or restarting the app, is a sensible first step. Organisations may want to check for messages or meeting invitations that failed to send during the outage, and to resend anything important.
What happens next
Companies that run on Microsoft's tools are likely to ask for a fuller explanation of what went wrong and how a repeat will be prevented. Microsoft has not yet set out every detail publicly, and more information is expected in the days ahead.
