Microsoft 365 outage hits North America after Outlook cyberattack series

newsbomb.gr (Greek) — November 12, 2026 at 08:01 PM UTC

Microsoft 365 experienced a major digital outage across North America on Thursday, disrupting core services including Teams, Outlook, Exchange Online, SharePoint Online, Copilot 365, and Defender XDR. Millions of users faced widespread connection failures as the company activated emergency protocols. Microsoft engineers halted new code deployments and initiated mass server restarts to address the failure, which followed a recent cybersecurity crisis. On November 10, the company released 1,094 security patches, closing a critical Outlook vulnerability (CVE-2026-124194) that allowed hackers to steal authentication data via malicious emails. The outage occurred just days after Microsoft resolved these active cyberattacks, which had enabled attackers to impersonate legitimate users without passwords. Network administrators worldwide, having just installed the massive security updates, now face renewed connectivity challenges as technicians work to restore services.
