Join and leave channels

Available on Entry, Professional, Enterprise, and Enterprise Advanced plans

Join a channel

Channels are either public or private.

• Public channels are identified with a Globe icon. Anyone on the team can join a public channel.
• Private channels are typically used for sensitive topics, and are identified with a Lock icon. You must be invited to private channels by another channel member.

iNote

To join a private channel, you need to be added to the channel by a member of that channel.

To join a public channel:

Web/Desktop

1. Select the Add channels button in the channel sidebar, then select Browse Channels.

Alternatively, you can select at the top of the channel sidebar, then select Browse Channels.

2. Select Join next to the public channel you want to join.

Mobile

1. Tap located in the top right corner the app.

2. Tap Browse Channels.

3. Tap the public channel you want to join.

+Tip

When you join channels, depending on the channel actions configured, you may see a welcome message, and channels may be added to a category in your channel sidebar automatically. Using Mattermost in a web browser or the desktop app, access Channel Actions from the channel name drop-down menu in the center pane to see what automatic actions have been configured.

• Create channels

Leave a channel

When you leave a private channel, you must be re-added by another channel member to rejoin. You won't receive mention notifications from a channel if you're not a member of that channel.

iNote

All users are added to the Town Square channel automatically. This means that users can't archive, unarchive, or leave the Town Square channel. However, guests who are manually invited to Town Square can leave the channel.

Leave a public channel added by a membership policy

From Mattermost v11.8.0, when you leave a public channel you were added to by a membership policy, Mattermost asks you to confirm:

• Choosing Leave channel removes you from the channel.
• Choosing Mute instead keeps you in the channel and mutes its notifications.

If the channel is already muted, Mattermost shows Cancel and Leave channel instead of Mute instead.
