Microsoft’s Outlook and Hotmail services experienced a significant outage early Tuesday. The disruption impacted hundreds of users across the UK and US.
As of midday, reports indicate that over 800 users in the UK faced difficulties accessing their accounts. Meanwhile, around 400 users in the US reported similar issues.
According to Downdetector, 64 percent of the reported problems were related to email login issues. Users are also struggling to receive messages.
Microsoft acknowledged the situation on its Service Health page. The company confirmed it is investigating the root cause of the server failures affecting both Outlook and Hotmail.
“Our investigation indicates client sign-in scenarios may be contributing to the reported behaviour,” Microsoft stated. They are focused on validating interactions across service components to identify next steps.
The outage began just before 10 AM on April 27, 2026. Users have expressed frustration over their inability to access essential email services.
Local fixes are unlikely to resolve the issues until Microsoft addresses server-side problems. The company has not disclosed a timeline for when normal service will resume.
This incident highlights ongoing challenges with Microsoft services, particularly regarding user access issues. Many rely heavily on these platforms for communication.
Further updates from Microsoft are expected as they continue their investigation into this widespread email outage.
The situation remains fluid, with no confirmation on when full functionality will return. Users are advised to monitor Microsoft’s channels for updates.
