Slack Channels Disappeared From the Sidebar? How to Get Them Back

Slack channels usually disappear from the sidebar because of a filter: Active only hides conversations with no new activity in 30 days, and muted channels can be hidden. Fix it from the Manage my sidebar menu. Other causes: collapsed sections, archived channels, leaving channels, the wrong workspace.

slack sidebar

Slack channels usually disappear from the sidebar because of a sidebar filter, not because they were deleted. By default Slack shows Active only, which hides conversations with no new activity in the past 30 days. Muted channels can also be hidden. To get them back on desktop, open the Home tab, click the Manage my sidebar icon at the top, hover over Filter and sort, and choose to show all conversations. In the same menu, choose Show muted conversations. If one channel is still missing, it was archived, you left it, or you were removed.

Sorting out your sidebar is quick. Sorting out your Slack presence is not: your dot turns grey 10 minutes after your last input in Slack, whatever you do in other apps. Slack Green keeps it green during the working hours you set, from the cloud, with nothing installed on your computer.

How to show all channels in the Slack sidebar

Show all your Slack channels again: Home tab, Manage my sidebar, Filter and sort, show muted

  • Click Home in the navigation bar.
  • At the top of the Home tab, click the Manage my sidebar icon.
  • Hover over Filter and sort and choose to show all conversations instead of Active only.
  • Open the same menu again and select Show muted conversations if it is there.
  • Expand any collapsed section by clicking its name.
  • Slack's help center describes the default this way: Active only hides conversations with no new activity in the past 30 days. That is why channels seem to vanish one by one over time, with no setting changed.

    Slack muted channels are hidden

If you muted a channel and then chose Hide muted conversations, every muted channel leaves the sidebar. They are still there, and you are still a member. Click Manage my sidebar and select Show muted conversations, or search for the channel and unmute it from its name menu.

One specific channel is gone

Search for it with the search bar or Ctrl+K / Cmd+K.

  • It opens, with a Join button. You left it, maybe through Clean up your channel list, which lets you leave channels you have not viewed in a while. Click Join.
  • It says the channel is archived. Archived channels drop out of every sidebar. A workspace admin or channel manager can unarchive it.
  • It does not come up at all. It is a private channel and you were removed, or it was deleted. Ask a channel member or an admin.
  • All my Slack channels disappeared

    When the whole sidebar looks empty:

  • Check the workspace. If you belong to several workspaces, use the workspace switcher and pick the right one.
  • Open Home. The Activity, DMs and Later tabs have their own lists; channels live on Home.
  • Check the view. Right-click the sidebar to switch between icons only and icons with text. Drag the sidebar edge if it is very narrow.
  • Reload. Restart the app, or press Ctrl+R / Cmd+R. If channels still do not load, check slack-status.com for an incident. If every coworker also looks offline, see Slack showing everyone offline.
  • Slack channels missing on iPhone and Android

    The mobile app follows the same account settings for muted conversations and sections. Channels hidden on desktop by a filter may still appear on mobile, and the reverse. Search in the app to open a missing channel, then star it or move it to a section so it stays easy to find.

    Keep important channels from disappearing

  • Star them or add a custom section (paid plans), so they stay at the top.
  • Unmute channels you need to watch.
  • Avoid Clean up your channel list for channels you read rarely but need.
  • If the thing that keeps disappearing is your custom status, not a channel, see Slack keeps clearing my status. For everything about the dot and status next to your name, start at the Slack status hub. If channels show but an unread badge will not clear, see Slack keeps showing unread messages.

    FAQ

    Why are my Slack channels disappearing from the sidebar?

    The default Active only filter hides conversations with no new activity in 30 days. Switch the filter to show all conversations under Manage my sidebar, Filter and sort.

    How do I display all my channels in the Slack sidebar?

    Click Manage my sidebar at the top of the Home tab, hover over Filter and sort, and choose all conversations. Then show muted conversations and expand collapsed sections.

    Why can't I see a channel in Slack?

    It is filtered out, muted and hidden, archived, or you are not a member. Search for it to find out which.

    Why are starred channels not showing up in my Slack sidebar?

    The Starred section may be collapsed, or the filter hides it when it has no recent activity. Expand the section and change the filter.

    Did Slack delete my channels?

    Almost never. Filters, muting and leaving hide channels from your sidebar only. Deleted channels are rare and done by admins.
