How to Remove Someone from a Slack Channel

Using the Desktop App

Open Slack. You must be a Team Admin or Owner to remove someone from a Slack channel. Open the Slack app on your computer (or click “Log In” at Slack.com to begin. If the channel is public, the person you remove will still be able to view the channel history and archived files. They can also rejoin the channel if they wish.

Sign into your team. If you’re not already logged in to your team, enter your team name and user credentials when prompted. You will arrive at your team’s default channel, usually #general. Note that you can’t remove a team member from #general (or other default team channels).

Join the channel. Click the name of the channel (e.g., “#channel”) on the left column to join.

Click the member list icon. It's the icon that looks like a cluster of profile photos at the top-right corner of the channel.

Click the user you want to remove. A small menu will appear.

Click the “Remove from #[channel]” link. Now you’ll see a confirmation screen appear.

Click “Yes, remove them” to save your changes. Slackbot will send a message to this team member to inform them that they’ve been removed.
