If you manage an Enterprise organization, you can control how members find and join your workspace.

Choose the right level of access:

• Open
  Anyone in your organization can view and join the workspace.
• By Request
  Any org member can request to join the workspace.
• Invite Only
  Any org member can be invited to join (may require Workspace Owner/Admin approval) or added to the workspace (by an Org Owner/Admin).
• Hidden
  Members cannot view the workspace and must be invited to join (by a Workspace Owner/Admin) or added (by an Org Owner/Admin). 

Note: Members can invite other org members into the workspace when the preference to allow members to send invitations is enabled. 

Tip: Members can read Join or leave workspaces in an Enterprise org for more details.

Set your access preference

Tip: Add a description about your workspace to help org members to find the right ones to join. From Workspace settings, click Change Workspace Info.

Approve a request to join

Requests to join your workspace will appear in a channel of your choosing.

Any person in that channel can approve the new request. To approve or deny it, click Add to Workspace or Don't Add to Workspace.
