Teams Discover feed Service migration [MC1120270]

Message ID: MC1120270

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.

What you can do to prepare

To ensure compatibility with the updated service, users must be on the following minimum client versions:

• Windows Desktop: Version 25020512900
• iOS: Version 2025031301
• Android: Version 2025031302

We recommend validating that your organization’s devices meet these version requirements before August 2025.

Compliance considerations

No compliance considerations identified, review as appropriate for your organization.
