MC1088172 - Microsoft Teams: New threaded conversation layout option for channels

Updated June 23, 2025: We have updated the timeline below. Thank you for your patience.

Coming soon to Microsoft Teams channels: A new threaded layout similar to group chats. Before this rollout, channels have a Post reply layout option only.

After this rollout, the threaded layout will encourage immediate back-and-forth communication in channels. In threaded layout channels, users can reply to specific messages and start a thread in the side pane. Threads allow users to have side conversations while keeping the main conversation without cluttering the main conversation.

This message applies to Teams for Windows desktop, Teams for Mac desktop, Teams for the web, and Teams for iOS/Android.

This message is associated with Microsoft 365 Roadmap ID 488300.

When this will happen:

Targeted Release: We will begin rolling out late June 2025 and expect to complete by early July 2025.

General Availability (Worldwide): We will begin rolling out mid-August 2025 and expect to complete by late August 2025.

How this will affect your organization:

After this rollout, to use threaded channels, users can either create a new channel and select Layout > Threads, or channel owners can use Edit channel to convert an existing posts channel to a threads layout.

Benefits of threaded layout channels:

• Provide a more collaborative layout for conversation in channels (no need to create a post to start a conversation)
• Provide a way for users to have deeper conversations on sub-topics
• Users can discuss multiple topics without disrupting the main conversation

Users can select Reply in thread to open the side pane and compose a message to start a thread on a sub-topic.

The Followed threads quick view shows users all the threads they're following across all channels in one place:

Admin controls

• This setting will be ON by default, allowing users to create threaded channels, or convert existing Post reply channels to the threaded layout.
• This setting can be applied to the whole organization, or just particular user groups.
• You will be able to turn off threading. You can find the global org-wide setting in Teams admin center > Settings & policies > Teams and channels > Teams settings. The setting will be called Threaded layout in channels.
• If users or channel owners turn off the setting, they will not be able to create new Threaded channels or convert channels to Threaded mode, but they will be able to continue using existing Threaded channels.
• To set threaded layout in channels as a user policy, go to Teams admin center > Settings & policies > switch tabs at the top to Custom policies for users & groups, and then create a new policy where you can turn off Threaded layout in channels.

Note: Admin control will be coming for General Availability, but will not be available in Private or Public Preview.

What you need to do to prepare:

This rollout will happen automatically by the specified dates with no admin action required before the rollout. Review your current configuration to assess the impact on your organization. You may want to notify your users about this change and update your relevant documentation.

Before rollout, we will update this post with new documentation.
