Using the Session Collaboration Feature
You can use the Session Collaboration feature to invite other users to join an existing remote desktop
session.
Invite a User to Join a Remote Desktop Session
When the Session Collaboration feature is enabled for a remote desktop, you can invite other users to
join an existing remote desktop session.
By default, you can send Session Collaboration invitations by email, in an instant message (IM), or by
copying a link to the clipboard and forwarding the link to users. To use the email invitation method, an
email application must be installed. To use the IM invitation method, Skype for Business must be installed
and configured. You can invite only users that belong to a domain that the server allows for
authentication. You can invite up to five users by default.
A Horizon administrator can disable the email and IM invitation methods, change the maximum number of
collaborators, and disable the Session Collaboration feature. For information about how the Session
Collaboration feature behaves at your company, contact your system administrator.
The Session Collaboration feature has the following limitations.
n
If you have multiple monitors, only the primary monitor is shown to session collaborators.
n
The Session Collaboration feature does not support PCoIP or RDP sessions. You must select the
VMware Blast display protocol when you create a remote desktop session.
n
H.264 hardware encoding is not supported. If the session owner is using hardware encoding and a
collaborator joins the session, both fall back to software encoding.
n
Anonymous collaboration is not supported. Session collaborators must be identifiable through
Horizon-supported authentication mechanisms.
n
Session collaborators must have Horizon Client 4.7 for Windows, Mac, or Linux installed, or they
must use HTML Access 4.7. If a session collaborator has an unsupported version of Horizon Client,
an error message appears when the user clicks a collaboration link.
n
You cannot use the Session Collaboration feature to share Linux remote desktop sessions or
published application sessions.
Prerequisites
To invite users to join a remote desktop session, a Horizon administrator must enable the Session
Collaboration feature.
