We're updating the backend service that powers the Teams Discover Feed. In mid-June 2025, the Discover Feed began transitioning from the People Prediction Service (PPS) to the Substrate Search Service Recommendations (3SR). This change is part of a broader infrastructure evolution to improve scalability and service integration.
When this will happen
This change began rolling out on June 18, 2025. The legacy PPS service will be deprecated starting August 2025.
How this affects your organization
There is no visible impact to end users or administrators. While the experience remains unchanged, this backend service transition ensures continued support and performance improvements.

To ensure compatibility with the updated service, users must be on the following minimum client versions:
- Windows Desktop: March 04 version i.e : 25031.805.3440.529
- iOS: Version 7.03.02 (100772025033501)
