System Requirements for the Session Collaboration Feature on Horizon Windows Client

With the Session Collaboration feature, users can invite other users to join an existing remote desktop session. To support the Session Collaboration feature, your deployment must meet certain requirements.

  • Session collaborators

    To join a collaborative session, a user must have Omnissa Horizon Client for Windows, Mac, or Linux installed on the client system, or must use Omnissa Horizon Web Client.

    Note: Horizon Web Client is available with Horizon 8 versions 2412 and later. For Horizon 8 versions 2406 and earlier, Horizon Web Client is called "HTML Access." This documentation page uses the name "Horizon Web Client" to refer to both Horizon Web Client and HTML Access.

  • Windows remote desktops

    The Session Collaboration feature must be enabled at the desktop pool or farm level. For information about enabling the Session Collaboration feature for desktop pools or farms, see the Desktops and Applications in Omnissa Horizon 8 document.

    You can use Horizon Agent group policy settings to configure the Session Collaboration feature. For information, see the Horizon Remote Desktop Features and GPOs document.

  • Linux remote desktops

    For Linux remote desktop requirements, see the Desktops and Applications in Horizon 8 document.

  • Omnissa Horizon Connection Server

    For Horizon 8 deployments, the Session Collaboration feature requires that the Horizon Connection Server instance uses an Enterprise license.

  • Display protocols

    Omnissa Horizon Blast

The Session Collaboration feature does not support published application sessions.
