Shared channel security and policies
Sharing a channel allows you to communicate with external organisations that you work with regularly, without leaving your own workspace. With this feature, we've taken added precautions to protect your privacy and keep your workspace or Enterprise Grid org secure.
Requests to share a channel
Approve a request to share a channel
Once an invitation to share a channel is accepted, it must be approved by someone from the organisation that owns the channel with permission to manage shared channels. If the member who accepted the invitation doesn’t have permission to manage shared channels, it must also be approved by someone from their organisation who does before the channel is shared.
By default, workspace owners and workspace admins on the Standard and Plus subscriptions, and org owners and org admins on the Enterprise Grid subscription can manage shared channels. If they like, they can also give members this permission.
When approving an accepted invitation, you’ll see the name of the external organisation and the person who accepted the invitation. Use this information to confirm that someone from your workspace or Enterprise Grid org would like to share the channel.
Decline a request to share a channel
If you're unsure what a proposed shared channel is for, or who sent the invitation, you have a few options:
- Don’t approve an accepted invitation to share a channel.
- Ask your members for more information if they're already working with the external organisation in some capacity.
- Contact the person who sent the invitation for clarification.
Message and file retention
Retention settings chosen for your workspace or Enterprise Grid org will apply to the messages and files sent by members of your organisation in shared channels. Anything sent by members of an external organisation in shared channels will be retained or deleted based on the retention settings chosen for their workspace or Enterprise Grid org.
Message editing and deletion
Message editing and deletion settings for your workspace or Enterprise Grid org will apply to messages sent in shared channels by members of your organisation. For example, an owner or admin can delete messages sent by members of their workspace in a shared channel, but not those sent by a member of an external organisation.
Export tools and data loss prevention
On the Standard and Plus subscription, workspace owners and workspace admins can use Standard Export to export content from public shared channels. On the Plus subscription, workspace owners can apply to access Corporate Export to export content from all shared channels (public or private) and the related direct messages shared across workspaces. All workspaces can read content or data posted in a shared channel, but only the workspace that sends the data can edit or delete it from Slack.
On the Enterprise Grid subscription, org owners can use e-discovery and data loss prevention (DLP) solutions for reviewing and regulating content. In shared channels, only messages and files sent by members of your organisation can be regulated and deleted with DLP solutions.
Note: Keep in mind that if an external organisation has applied custom retention settings for their workspace or Enterprise Grid org, this will impact the data that can be exported.
