Browsing the All unread view on desktop lets you catch up on the messages you missed when you were away from Slack. While you’re at it, you can act on those messages too:
Scan what's new and mark channels as read
Add a reaction to a message, start a thread or show message actions
Jump from the All unread view to a channel to post a new message
Keep in mind: for now, all unreads is only available on desktop. Stay tuned for updates! 📰
Set your All unread view
From your desktop, click your workspace name in the top left.
Select Preferences from the menu.
Click Sidebar.
Tick or untick the box next to Show all unread.
Note: Messages in muted or archived channels aren’t included in the All unread view.
Navigate unread messages
Sort unread channels
Decide how to prioritise your unread messages by changing how they’re sorted. You can sort messages alphabetically, by newest activity or by oldest activity. On paid subscriptions, you also sort scientifically – a view tailored to how you use Slack.
Mark messages as read
Click Mark as read to clear that channel’s messages once you’ve finished reading them. You can also scroll to the bottom of the All unread view and click Mark all messages read.
If you clicked Mark as read too quickly, just click Undo to keep those messages in your All unread view.
Save a channel’s messages for later by clicking thearrow icon beside the channel name to collapse it. Click the arrow again when you’re ready to read the unread messages.
Refresh for new messages
When new messages become available while in the all unread view, the syncing arrows icon will appear in the header. Click the icon to reveal a fresh batch of unread messages!
