Microsoft Outlook is experiencing a widespread service outage on Thursday, leaving millions of users unable to access their email accounts and related Microsoft 365 services. The disruption began around 12:00 p.m. ET and quickly escalated, with error reports surging on monitoring platforms like DownDetector.
By 1:12 p.m. ET, the service had logged over 130,000 user reports, indicating serious issues with the popular email platform. The outage extended beyond Outlook, affecting other Microsoft services such as Microsoft 365, Microsoft Copilot, and Microsoft Teams.
The scope of the problem became more apparent when Microsoft’s own service status page failed to load for some users attempting to check on the outage. This suggested the issue was more widespread than initially apparent and potentially affected Microsoft’s infrastructure more broadly.
Microsoft Acknowledges Broader Impact
In an updated statement posted to X, Microsoft acknowledged that the issue extended beyond the Americas and affected additional services. The company stated, “While we’re working to mitigate impact, we’ve confirmed the issue may affect Microsoft 365 service connectivity for users in any region. More information will be provided in the Microsoft 365 admin center under EX1550543.”
Microsoft further explained the technical nature of the problem, noting that “a portion of infrastructure is experiencing elevated load across multiple regions, which is likely contributing to the connectivity errors.” This statement indicated that the root cause involved infrastructure strain rather than a localized issue.
Another Major Outage for Outlook
This incident marks another significant service disruption for Microsoft Outlook in recent months. The email service previously experienced a widespread outage in August 2026, during which Microsoft attributed the problem to a misconfiguration issue that prevented authentication components from deploying correctly.
Users are advised to monitor Microsoft’s official communication channels for updates on the resolution of the outage. The incident highlights the importance of reliable email services in both personal and professional contexts.
