When a channel is no longer needed, it can be archived or deleted (except for the the #general channel or #all-companyname channel). Archived channels are closed to new activity, but the message history is retained and searchable on paid plans. Deleted channels are permanently removed from a workspace, message history included.
Click the channel name in the conversation header.
Click Settings, then Archive channel for everyone.
Click Archive channel to confirm.
If you set up your channel with a template, the canvases and lists will remain accessible in Slack, while the workflows will be unpublished. To delete a canvas, list, or workflow added as part of a template, check the box next to its name, then click Delete.
Open the channel you'd like to archive.
Tap the channel name in the conversation header.
Tap Archive channel. Scroll down if you don't see the option.
If you change your mind, you can unarchive a channel. If the channel is private, the channel members will be retained, but if it's public, the former members will not be restored.
From Home, click Directories.
Click the Channels tab.
Search for the channel by name or description, or click the Channel type filter and select Archived channels.
Select the channel you'd like to unarchive from the list.
Click the channel name in the conversation header.
Click Settings, then click Unarchive this channel.
Note: If you don't see Directories, look for the Channels tab in the sidebar instead. You may need to click More to find it.
Tip: Channel names can't be repeated. To reuse the name of an archived channel, you'll need to unarchive it and rename the channel.
