What is changing?
Microsoft is retiring the legacy Turnitin Similarity integration in Teams Assignments and recommending customers migrate to the Turnitin Feedback Studio integration.
Why is Microsoft making this change?
Turnitin Feedback Studio is the strategic long-term experience supported by Turnitin and provides a broader instructor workflow experience. Microsoft is also reducing ongoing operational and sustaining engineering burden associated with the legacy integration.
When will the Similarity integration stop working?
The standard retirement date for the legacy Similarity integration is planned for December 31, 2026.
Why was the retirement date selected?
The date was selected to align with the end of the Southern Hemisphere academic year while also encouraging Northern Hemisphere institutions to complete migration during Summer 2026 before the next school year begins.
What should Northern Hemisphere institutions do?
Northern Hemisphere institutions should strongly consider completing migration during Summer 2026 to avoid disruption during active academic terms.
What is the recommended replacement?
Microsoft recommends the Turnitin Feedback Studio integration for Microsoft Teams.
Where can I find migration guidance?
The Turnitin team will be reaching out to you directly with migration details from msteamsmigration@turnitin.com. They will provide comprehensive training and support resources to ensure your upgrade to Turnitin Feedback Studio is as efficient as possible.
Will the product display migration warnings?
Microsoft plans to introduce in-product notices to educators using this feature later in 2026.
