Introduction
We're excited to announce that Microsoft Teams now supports apps in Private channels. This update enables richer collaboration scenarios across teams and organizations by allowing users to add and use apps-including bots, tabs, and message extensions-directly within Private channels. This change aligns with customer feedback requesting more consistent and flexible app experiences across collaboration spaces. Support for apps in Private Channels follows the same model as that for shared channels, ensuring a unified experience for users and developers.
This message is associated with Roadmap ID 518215 and applies to Teams for Windows desktop and Teams for Mac desktop.
When this will happen:
Targeted release: Rollout begins mid-January 2026, and we expect to complete by late January 2026.
General availability (Worldwide): Rollout begins late February 2026, and we expect to complete by late March 2026.
