(Updated) New in Teams – open channels in dedicated windows [MC1162964]

Message ID: MC1162964 (Updated)

Updated December 16, 2025: We have updated the timeline. Thank you for your patience.

[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.

This change is associated with Microsoft 365 Roadmap ID: 509110

[When this will happen:]

General Availability (Worldwide): Rollout will begin in late October 2025 and is expected to complete by late January 2026 (previously 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.

[What you can do to prepare:]

• No admin action is required.
• You may choose to:
  • Inform helpdesk and support staff of the new multitasking capability.
  • Update internal training or documentation if you provide Teams usage guidance.

[Compliance considerations:]

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