Dear colleagues,

Microsoft is introducing two user interface updates in Microsoft Teams to improve navigation and conversation organization.
These changes are rolling out automatically and do not require administrative action.

What is changing

• • Simplified Teams app bar
    The Teams app bar on desktop (Windows and macOS) will display fewer items by default.
    Overflow apps will move to a “View more apps” menu.
    Users can show or hide the app bar to create more workspace.
  • Default threaded layout for first channel in new teams
    For newly created teams, the first channel will default to a threaded (conversation) layout instead of Posts.
    This aligns with the default behaviour of new channels and supports clearer discussions.

 

Who is affected

• • All Microsoft Teams desktop users (app bar update)
  • Users participating in newly created Teams (channel layout change)

 

Action required

• • No action is required.
  • Optional:
    • Use keyboard shortcuts to show or hide the Teams app bar:
      • Windows: Ctrl + \
      • Mac: Cmd + \
    • Team owners can switch channel layout from threaded to Posts if preferred.

 

Timeline

• • App bar simplification:
    • General Availability: End of April 2026
  • Default threaded channel layout:
    • General Availability: Early May 2026 (rollout expected to complete in early May 2026)
