Microsoft apologises and explains what is causing Outlook, Teams outage
Microsoft has apologized for a global service outage that affected Outlook, Teams, and Copilot for nearly 24 hours. The company attributed the disruption to a technical error during a network capacity upgrade rather than a cyberattack.
Why it matters
As businesses rely heavily on cloud-based infrastructure, outages of this scale highlight the fragility of global digital ecosystems and the importance of robust network management.
Microsoft has apologised for the global outage that knocked Outlook, Teams and Copilot offline for millions of users for the better part of a day. It has also finally explained what went wrong. The company says the disruption was caused by "a technical issue not related to cyber or AI / agents." It traces the problem to an earlier network capacity upgrade, where a fault crept in and only showed itself after a more recent network change.The explanation comes nearly 24 hours after users first began reporting trouble on Thursday, around noon US Eastern time. That was close to 10:30 pm in India. Microsoft says it has fixed the underlying issue and is seeing "broad recovery and stability" across its services.
