MC1162964: New in Teams – open channels in dedicated windows

Microsoft Teams will let users open channels in separate windows for better multitasking, rolling out worldwide from late October to November 2025. This feature is enabled by default for all desktop users, requires no admin action, and does not affect existing functionality or policies.

[Introduction]

We're introducing a new productivity feature in Microsoft Teams: Open Channels in a New Window. This enhancement allows users to detach any channel from the main Teams client and view it in a separate window—supporting better multitasking and focus, especially in high-traffic or cross-functional collaboration scenarios.

General Availability (Worldwide): Rollout will begin in late October 2025 and is expected to complete by late November 2025.

[How this affects your organization:]

  • Who is affected: All users of Microsoft Teams desktop client (Windows and macOS).
  • What will happen:
    • Users will find a new option to Pop out channel from the channel menu.
      • The channel will open in a separate window, allowing simultaneous viewing of multiple channels.
      • There are no changes to existing Teams functionality or policies.
      • Feature will be enabled by default for all tenants.
