Microsoft has confirmed it is investigating a significant issue affecting Microsoft Teams for Education, which is particularly impacting users’ ability to access critical features such as assignments and grades.

The problem, which initially appeared limited to administrators in Europe, has since expanded to affect all users with educational accounts worldwide potentially.

The outage stems from backend infrastructure challenges within Teams’ processing systems. Microsoft first acknowledged the issue on November 12, 2025, stating that affected admins in the European region were unable to open or load assignments and grades.

This disruption has broader implications for educators and students relying on the platform for daily collaboration and academic management.

As the investigation progressed, Microsoft updated its status to reveal that the issue extends beyond admins to any user holding a Microsoft Teams Educational account.
