Microsoft has publicly apologised for a global outage that knocked several of its most-used services Outlook, Microsoft Teams and Copilot- offline for nearly 24 hours. Businesses, government agencies, airlines and millions of users in many countries were affected by the outage, which raises fresh questions about the reliability of cloud-based services that have become essential to everyday life.
The tech giant admitted the incident was serious and said it was sorry for the inconvenience caused to customers and business partners. In an official statement, Microsoft said it was seeing broad recovery and stability across services, engineers were working to restore access in remaining regions and “some progress has been made”. But there was no clear timeline for full restoration, yet some users were left wondering when all services would be back to normal.
Microsoft said the outage was caused by a technical problem related to an earlier capacity upgrade on its network. The issue came up after more recent changes in its network changed the availability and performance of its infrastructure.
Microsoft said the incident was not caused by a cyberattack or artificial intelligence systems or AI agents. It said it had resolved the technical problem but was working to get services back online for those who were still having problems. The clarification came as fears grew that a security breach or malicious activity may have been behind the widespread disruption.
Several key Microsoft products and services were impacted: Outlook, which is widely used for professional and personal email communication; users of Microsoft Teams had trouble accessing workplace chat tools (chats) and meetings; Microsoft 365 Copilot and other cloud services were disrupted as well (organisations that use Microsoft’s digital ecosystem every day suffered).
At its peak, the outage generated more than 130k reports on Downdetector about Outlook problems. Reports of service disruptions came in from 74 countries/territories on an international scale.
The effect was felt in India too, where airline companies said their email-based customer support systems were down. IndiGo told passengers that its email support services had been disrupted and the airline may not be able to receive emails from customers during this period.
Akasa Air said it had delays with email support operations and asked passengers who needed immediate assistance to contact the 24/7 customer care centre or social media channels. Air India said flights continued as normal but temporarily rerouted email services so that communications with customers did not stop. These examples showed how a technical failure involving one major technology provider can cause problems for businesses and customer-facing services across industries.
Microsoft also explained why it was taking longer than expected to recover. Instead of restarting all affected infrastructure at once, the company restored services in stages; engineers brought systems back online one by one while watching how they were performing and checking whether the infrastructure could cope with normal levels of demand.
Microsoft said this was needed because stability had to be maintained and further disruption prevented. “While gradual restoration took more time, we felt that it reduced the chance of another failure as traffic returned to the affected systems,” it added. Email delivery and service availability reportedly improved in several regions as recovery operations progressed.
The nearly 24-hour outage has once again prompted questions about how businesses and institutions are becoming dependent on a small number of major cloud technology providers; corporate communications, customer support, government operations and workplace productivity all rely on Microsoft services.
When a major platform fails (and it did), the effects go well beyond individual users not being able to access their emails: Businesses may delay communication; employees might struggle to get work done; customers may have trouble getting through to service providers.
Microsoft has apologised for the inconvenience and said it takes the trust placed in its services very seriously. It has reported broad recovery, but users in some regions may still experience intermittent problems as the remaining systems come back online. The company is also expected to give further technical details about the incident. For now, though, the global outage is another reminder that even the world’s biggest technology companies aren’t immune to infrastructure failure, so backup systems and alternative communication channels are more important than ever for businesses and organisations.
