Add channel members without joining

Overview

Administering messaging at scale used to require unnecessary steps. In large deployments where app managers oversee hundreds of channels, they had to join every public or private channel just to perform administrative actions. This created problems:

• Manual overhead for routine channel administration.

• Membership lists filled up with administrators who were there only for management purposes.

• Blurred lines between administrative access and conversation participation.

• Harder private-channel governance in large environments.

The 26.08 update separates channel administration from channel participation. App managers can now perform membership management tasks without joining the channel first. Administrative authority no longer requires visible channel membership.

What changed

This enhancement introduces a new administration model for messaging channels across web and mobile:

• Public channels: App managers can add members without joining the channel.

• Private channels: App managers can add members without joining the channel.

• Mobile support: The same capability is available on iOS and Android.

• Private channel settings on mobile: The mobile work also covers updates for private-group settings and related UI handling.

Why this matters

App managers overseeing hundreds of channels in large deployments benefit most from this change.

Operational improvements

• App managers can administer many channels without repetitive join-and-leave workflows.

• Membership lists better reflect actual participants rather than administrators performing occasional maintenance.

• Admins can add people to the right channels more quickly.

• App managers can still administer sensitive or limited-access channels without changing visible membership.

Governance improvements

• Being an app manager gives management capability, not implicit conversational participation.

• Private channels remain private in terms of participation and visibility expectations.

• The feature aligns with how large organizations separate platform governance from day-to-day conversation membership.

Best practice: Use this capability for channel administration and governance, not as a substitute for joining channels where active participation, monitoring, or response is actually required.

How the permission model works

The new model preserves privacy and access controls while removing the need for administrative membership. The goal is to enable administration without channel membership while preserving privacy, security, and channel governance.

What the change does

• App managers can perform supported membership-management actions without first joining the channel.

• Administrative access remains role-based and depends on existing permission checks.

What the change does not do

• It does not make app managers channel members by default.

• It does not grant blanket rights to edit or rewrite other users' messages.

• It does not change the distinction between public and private channels as participation spaces.

• It does not remove existing audit, policy, or organizational governance expectations.

Important: A related 26.08 change restricts message editing so that only the message author can edit their own message. This applies even to elevated roles such as app managers and messaging group managers.

Supported platforms

How to add a member without joining the channel

The exact UI varies slightly by surface, but the flow is the same:

1. Open the messaging channel that needs administration.

2. Go to the channel or group member-management area.

3. Use the add-member action.

4. Select the user or users to add.

5. Save the change.

The app manager does not need to join the channel first.

Best practices for administrators

• Limit the app manager role to trusted users. Administrative capability should not be handed out broadly.

• Periodically review who holds the app manager role and whether those users still need messaging administration access.

• Use this capability for governance work, not as a substitute for joining channels where active participation is required.

• Remember that private channels remain private. Adding members administratively does not grant the app manager visibility into channel conversations.
