User manual

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.

published application sessions.

The collaboration icon looks different depending on the Windows operating system version.
3 When the VMware Horizon Collaboration dialog box opens, enter the user name (for example,
testuser or domain\testuser) or the email address of the user that you want to join the remote
desktop session.
The first time you enter the user name or email address of a particular user, you must click Look up
"user", enter a comma (,), or press the Enter key to validate the user. The session collaboration
feature remembers the user the next time you enter the user's user name or email address.
You can invite up to five users by default. A Horizon administrator can change the maximum number
of users that you can invite.
