Microsoft’s Outlook email hit by new outage

AI-summarised brief · reviewed before publication

Microsoft confirmed an outage affecting its Outlook email service, blocking access for both business and consumer accounts worldwide. The disruption, first reported in the United States and the Americas, quickly spread to all regions and also impacted Teams, SharePoint, Copilot, Defender XDR, OneDrive, and Office for the web. Microsoft’s admin center was unavailable, leaving administrators without status updates. In a post on X, the company said an “elevated load” on infrastructure forced it to redistribute traffic across its global network. A later update blamed “a large number of servers being unexpectedly unavailable,” though no cause was disclosed. The incident follows a September Microsoft 365 outage linked to a core authentication configuration problem, and investigations remain ongoing for users worldwide today.
