Assessment Reasoning
The change requires admins to identify and coordinate updates for custom LOB apps to support private and shared channels, which demands testing and developer involvement. Failure to update will block app functionality in these channel types, creating user gaps in workflows. Rollout is imminent and guidance is already available, so planning and coordination should begin promptly.

ROLLOUT TIMELINE

Upcoming:
September 2026

📢 Official Microsoft Message Center Announcement

Microsoft Teams: Prepare custom apps for private and shared channel compatibility
Message ID: MC1459131

[What and Why:]

Microsoft will begin rolling out a new feature in Teams admin center that helps admins identify custom line-of-business (LOB) apps that need updates to work in private and shared channels. Taking action now will help organizations ensure apps are available in these channels and work smoothly across evolving channel experiences.

This message is associated with Microsoft 365 Roadmap ID 569019

[Rollout Schedule:]

General Availability (Worldwide): We will begin rolling out on early September 2026 and expect to complete by late September 2026.

[Impact on your organization:]

If apps are not updated to support private and shared channels, users may be unable to access those app experiences in these channels until the required updates are completed.

Why this is important:

  • Business continuity: As organizations adopt private and shared channels, updating LOB apps helps reduce the risk of app access gaps across channels.
  • Lower operational overhead: Completing these updates early can help reduce admin escalations, helpdesk tickets, and reactive fixes.

What you can expect

Admins will be able to view a list of custom LOB apps that are not compatible with private and shared channels in the Teams admin center under Teams apps > Manage apps.

21622

Guidance is available now, enabling organizations to work with custom LOB app developers to plan and complete the required updates. Developers can review the documented requirements, update their apps, and validate supported scenarios.

[Action Required / Recommendations:]

  • Review custom apps used in team and channel scenarios across your organization.
  • Ask your app developers to complete the required updates for private/shared channel scenarios.
  • Validate that updated apps continue to support the scenarios your users rely on.
