Shared channels is a brand new feature that lets two separate workspaces communicate securely in Slack. You can share any channel on your workspace to another team’s workspace — like clients, customers, or contractors you work with regularly.

• Create a common area between two unique workspaces, so you can find everything you need in one place.
• Simplify communication, streamline conversations, and gain efficiency.
• Make information and context easier to find across workspaces.

Beta: Workspaces on Slack Enterprise Grid can connect shared channels to other workspaces in their organization, but it’s not possible to create a shared channel with an external workspace at this time.

Try the beta

Workspace Owners and Admins can opt in to join the shared channel beta. If you opt in, your entire workspace will automatically receive shared channel feature updates as soon as they become available.

Some features won’t be fully supported during the beta, but they will be released later:

• In this beta, only public channels can be shared. Private shared channels aren’t yet available.
• Custom message and file retention settings, set by either workspace, do not apply to shared channels while in beta — all messages and files will be retained unless they are manually deleted.
