Is Outlook down? Possible Microsoft outage locks down email inboxes.

On Thursday, Nov. 12, users reported significant difficulties accessing Microsoft Outlook, a widely used email service. The issue originated in the Americas but soon extended to other regions, affecting multiple Microsoft 365 services including Teams, Exchange Online, SharePoint Online, Microsoft Copilot 365, and Microsoft Defender XDR.

Microsoft's status page was initially unavailable, but later indicated that an unknown portion of infrastructure was experiencing elevated load, potentially contributing to the connectivity errors. The company acknowledged that the issue may impact services for users in any region and is working to mitigate the impact. As of 1:12 p.m. ET, the service had received over 130,000 reports of issues, suggesting a widespread problem.

The Microsoft 365 Status account on X tweeted an acknowledgment of the ongoing investigation into the issue. This is the latest in a series of major outages for Microsoft's Outlook service, with the previous one in August being attributed to a misconfiguration issue.
