Sharing a channel with external organisations lets you work together in a single channel that you can all access from your own workspaces. If another organisation has invited you to share a channel, keep reading for details on accepting the invitation and how it gets approved.
What to expect
Someone from the organisation that owns the channel will send you an invitation link. If multiple people from your organisation receive an invitation to share the same channel, only one person needs to accept it.
Once an invitation is accepted, it must be approved by someone from the organisation that owns the channel. If the member who accepted the invitation doesn't have permission to manage shared channels, it must also be approved someone from your organisation who does.
Invitation links expire after seven days. If your invitation expires before it’s accepted or approved, ask the channel owner to send you a new invitation link.
To decline a shared channel invitation, simply ignore the request.
Note:To accept an invitation, your organisation must be using one of Slack’s paid subscriptions. If you're using the free version of Slack, learn how to upgrade your workspace.

Once you or someone from your organisation accepts an invitation, it will be sent to the organisation that owns the channel for approval. If the member from your organisation who accepted the invitation doesn’t have permission to manage shared channels, the request will also be sent to your organisation for approval.
