What and Why
Microsoft is retiring the Turnitin Similarity integration in Microsoft Teams Assignments and encouraging institutions to transition to Turnitin Feedback Studio for Microsoft Teams. Turnitin Feedback Studio provides similarity checking, grading, feedback, and assignment management within Teams. For sustainability and fairness in its partner ecosystem, Microsoft Education is phasing out non-standard integrations with third party products such as the Similarity integration in Teams Assignments. Turnitin’s Feedback Studio integration is built for the long-term, using standard platform extensibility features.
