Microsoft has stated that it is looking into a severe issue with Microsoft Teams for Education, which is limiting users’ ability to access important functionality such as assignments and grades.
The issue, which appeared to be limited to administrators in Europe at first, has recently spread to possibly affect all users with educational accounts worldwide.
The downtime is the result of backend infrastructure issues with Teams’ processing systems. On November 12, 2025, Microsoft first confirmed and announced that affected administrators in the European region were unable to open or load assignments and grades.
According to Microsoft, the disruption affected educators and students who use the site for daily collaboration and academic management.
Microsoft had revealed that, as the inquiry went on that the problem affects those users with Microsoft Teams Educational accounts, not only administrators.
The platform’s importance in contemporary remote learning settings is highlighted by this escalation, since even short outages can prevent lesson planning, grading, and student interactions.
Microsoft engineers and experts are actively restarting crucial backend components that drive Teams’ services in order to fix the issue. Restoring processing capacity and lessening the ongoing impact are the goals of these restarts.
For real-time updates, users who are having trouble are referred to the Microsoft 365 admin centre under incident identification TM1185134. IT administrators may track resolution activities with the support of comprehensive timelines, impacted services, and mitigating procedures.
This incident’s timing is especially regrettable because it falls during the midterm, when academic institutions rely significantly on digital resources.
Millions of people worldwide use Microsoft Teams, a component of the larger Microsoft 365 package, which has capabilities tailored to education that are firmly ingrained in school processes.
Previous Teams failures have frequently featured high-traffic circumstances or setup difficulties in cloud infrastructure, albeit the firm has not identified an underlying reason, such as a software bug, server overload, or external source.
Microsoft highlights the fact that its teams are working nonstop to address the problem, and when restarts are finished, early indications of improvement are anticipated.
Also too, Microsoft posted on its X (formerly twitter) account that its ‘’monitoring indicates that customers are experiencing some recovery from our mitigation efforts. We are focused on connecting additional backend infrastructure to expedite recovery while continuing to analyse the errors to identify the root cause and determine next steps.’’
In the meanwhile, concerned users should watch the admin centre and look into other alternatives for important work. This episode shows the continued problems of maintaining dependable cloud-based educational platforms, particularly in light of increased demand post-pandemic.
Educators and IT workers should develop contingency plans to minimise academic disruptions when additional information about TM1185134 becomes available. Microsoft has agreed to conduct a thorough post-incident investigation to avoid similar incidents in the future.
