Microsoft apologises and explains what is causing Outlook, Teams outage; says: ‘Not related to cyber or AI’
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.
