With the Session Collaboration feature, end users can invite other users to join an existing remote desktop session.
To enable remote desktop users to collaborate, a Horizon administrator must enable the Session Collaboration feature for the desktop pool that provides the remote desktop. For RDS desktop pools, a Horizon administrator must enable the session collaboration feature for the farm on which the RDS desktop pool is based.
To enable invited users to join sessions from pods other than the session owner's pod, you must enable the Session Collaboration feature for the global desktop entitlement that contains the desktop pool.
Session Collaboration is not supported for published applications. For complete requirements and limitations, including licensing requirements, see "Configuring Session Collaboration" in the Configuring Remote Desktop Features in Horizon 7 document.
