Microsoft acknowledged the problem via its service health status page, advising affected users to check for updates outside the inaccessible portal. Microsoft recommends using alternative URLs, like the Microsoft 365 admin center direct links or the service health dashboard, for updates. Microsoft is currently facing an outage that affects the Microsoft 365 Admin Center, preventing administrators from accessing essential management tools. The outage has left admins unable to monitor service health, manage user accounts, or perform essential configurations, potentially halting IT operations across organizations. Microsoft attributes it to a portion of the system not meeting expected thresholds, similar to past issues involving buggy updates or routing errors. The Admin Center serves as the central hub for managing Microsoft 365 services, including Exchange Online and Teams. The outage primarily impacts admins routed through affected US East region infrastructure, but reports suggest a broader global reach, including Europe and Asia. Thousands of Microsoft 365 administrators with business or enterprise subscriptions are directly affected, encountering “Runtime Error” messages when attempting to log in. Microsoft has not disclosed the exact number of affected users, but confirms it’s tracking the incident under MO1120879. The issue, which emerged prominently on July 24, 2025, has persisted into the following day, marking the second such incident this week and raising concerns about service reliability. As businesses rely heavily on Microsoft 365 for operations, this disruption underscores the vulnerabilities in cloud-based infrastructure. This has ripple effects on end-users, as admins cannot address service issues promptly, potentially leading to delays in resolving email, Teams, or other application problems. As of July 26, 2025, Microsoft continues mitigation efforts, with full resolution expected soon. The current issue follows a similar disruption on July 24, where Eastern US infrastructure failed to meet performance thresholds. Admins should monitor the official Microsoft 365 Status account on X for real-time information. This adds to a pattern of 2025 outages, including a 19-hour global disruption earlier in July linked to configuration changes. Preliminary investigations point to underperforming regional service infrastructure, causing authentication and access failures.
