UPDATE: Microsoft Says New Fix Returns Some Microsoft 365 Servers to Service
Microsoft says an alternate server health check has restored a subset of affected servers, with a wider rollout under way. Microsoft 365 service degradation continues; full restoration has not been announced.
Microsoft says it has brought a subset of affected Microsoft 365 servers back into service after validating an alternative service health check, a sign of recovery progress during Thursday's disruption.
In a 4 PM Eastern update, the company said it was applying the change more broadly. It was also preparing automated recovery systems to detect and restart unresponsive servers while the change progresses.
As previously reported, Microsoft had confirmed email-access problems and said related Microsoft 365 connectivity issues could affect users in any region.
The new update does not mean that all users or all affected services have recovered. Microsoft's public service-health page continued to show degradation for Microsoft 365 business and enterprise services when checked for this report.
Microsoft directs administrators to incidents EX1550543 and MO1550821 in the Microsoft 365 admin center. Its public status page is available when administrators cannot access the admin center.
The company has not announced full restoration in the update reviewed for this report. Users should check Microsoft's current service-health notices for changes in availability.
