By rssfeeds-admin The company’s official Microsoft 365 Status account on X confirmed the incident, noting the last status update at 10:15 AM UTC.
Users across multiple regions are experiencing disruptions when attempting to access Outlook.com, including intermittent failures to load the inbox, delayed email delivery, and complete inability to reach the webmail interface.
The outage is part of a broader pattern of Microsoft 365 service instability that has dogged the platform throughout early 2026, following a significant multi-service disruption in January that affected Outlook, Microsoft Teams, Defender, and SharePoint.
Microsoft’s official service health dashboard listed the event under “Service Degradation” — a classification used when core functionality is impaired but not entirely offline — distinguishing it from a full outage scenario.
A separate but related degradation affecting Outlook Classic with the Microsoft Teams Meeting Add-in has been confirmed as triggered by an incompatible legacy Outlook build version remaining active in certain user environments.
Microsoft confirmed on April 27 at 08:58 AM UTC that the fix deployment is continuing to progress as expected and is scheduled for completion by Tuesday, April 28, 2026.
As a temporary workaround, Microsoft has advised affected users to follow steps published in the admin center’s More Info section to bypass impact while the broader rollout completes.
The company also noted that temporary version restrictions placed on some users will be lifted once the fix is fully deployed.
This latest incident adds to growing concerns over Microsoft 365 reliability. In April 2026, an earlier outage took down Microsoft 365, Teams, Outlook, and Azure simultaneously, with Microsoft attributing the disruption to an external service dependency affecting multiple platform components.
The January 22, 2026, incident similarly forced Microsoft engineers to implement load-balancing efforts and targeted server restarts to restore normal operations.
Users and administrators can monitor live service health at status.cloud.microsoft or check the Microsoft 365 admin center under Health > Service Health for real-time incident updates.
Organizations relying on Outlook.com for critical communications are advised to implement contingency email procedures until full service restoration is confirmed.
