Outlook is down, and so is Microsoft's status page

Commenters described a Microsoft service outage affecting Outlook, Exchange, Teams, SharePoint, Partner Center, and related integrations, while Microsoft’s status page was also difficult to reach. One commenter relayed updates saying servers were failing automated health checks, apparently after a component change; the failures took servers out of service, shifting load to those still running. Microsoft was redistributing traffic, pausing deployments, testing a configuration change, and restarting affected servers. Some workers said email and Teams were unavailable across their organizations, while others reported intermittent errors or said particular services still worked.

Views differed on the outage’s cause, scope, and significance. Several commenters criticized Microsoft’s reliability and opaque, jargon-heavy updates, and argued that the status page should withstand a surge during an outage. Others cautioned that DownDetector reflects user reports and can misidentify affected services, especially when SSO or other shared infrastructure is involved. Commenters also objected that “new Outlook” routes even some self-hosted email through Microsoft’s cloud, extending the outage to customers who believed their systems were independent; others said this setup was not typical for on-prem Exchange users. Some mocked the server restarts as amateur practice, while others defended rebooting as a sensible first step. Broader complaints about Microsoft’s software and Teams reliability contrasted with praise for Google’s user experience and Slack’s stability.
