Microsoft Outage Map: Several Microsoft services, including Teams, Outlook, and Defender, experienced massive downtime on Thursday. Downdetector, a platform that tracks online outages, showed at least 15,000 reports about Microsoft 365 at the time of writing this story.
Downdetector also showed an outage for Mimecast, GoDaddy, and other apps. However, the AWS server status page showed no problems.
“We are investigating a potential issue affecting multiple Microsoft 365 services, including Outlook, Microsoft Defender, and Microsoft Purview. More information can be found in the admin center under MO1221364,” Microsoft said in a statement on X, a platform formerly known as Twitter.
“We have identified a portion of the service infrastructure in North America that is not processing traffic as expected. We are working to restore the infrastructure to a healthy state to achieve recovery,” he added in an update.

Downdetector published an outage map showing cities such as Los Angeles, Minneapolis, Phoenix, Dallas, Houston, San Francisco and Seattle affected by the issues.
Microsoft acknowledged a service outage affecting multiple Microsoft 365 products, with users reporting errors when accessing email, collaboration tools, and administrative portals across North America.
According to the company’s official status page, some users are encountering a “451 4.3.2 temporary server issue” when trying to send or receive emails through Outlook. The outage is impacting several core features, including email delivery in Exchange Online, tracking of delayed or failed messages, and disruptions to searches within SharePoint Online and OneDrive.
Access to key service portals, such as Microsoft Purview, Microsoft Defender XDR, and the Microsoft 365 admin center, has also been intermittently affected.
Microsoft said engineers are working to restore the affected infrastructure to a healthy state and rebalance service traffic. The company attributed the issue to some of the dependent service infrastructure in North America not processing traffic as expected, adding that users in the region may continue to see intermittent outages until recovery efforts are complete.
