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 (Windows remote desktops only), 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 for a Windows remote desktop, 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.
The Session Collaboration feature has the following limitations.
- If you have multiple monitors, only the primary monitor is shown to session collaborators.
- You must select the VMware Blast display protocol when you create a remote desktop session. The Session Collaboration feature does not support PCoIP or RDP sessions.
- 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.
- Anonymous collaboration is not supported. Session collaborators must be identifiable through Horizon-supported authentication mechanisms.
- Session collaborators must have Horizon Client 4.7 or later for Windows, Mac, or Linux installed, or they must use HTML Access 4.7 or later.
- If a session collaborator has an unsupported version of Horizon Client, an error message appears when the user clicks a collaboration link.
- You cannot use the Session Collaboration feature to share published application sessions.
To invite users to join a remote desktop session, a Horizon administrator must enable the Session Collaboration feature.
For Windows desktops, this task includes enabling the Session Collaboration feature at the desktop pool or farm level. It can also include using group policies to configure Session Collaboration features, such as the available invitation methods. For complete requirements, see Requirements for the Session Collaboration Feature.
For information about enabling the Session Collaboration feature for Windows desktops, see the Setting Up Virtual Desktops in Horizon 7 document. For information about enabling the Session Collaboration feature for a farm, see the Setting Up Published Desktops and Applications in Horizon 7 document. For information about using group policy settings to configure the Session Collaboration feature, see the Configuring Remote Desktop Features in Horizon 7 document.
For information about enabling the Session Collaboration feature for Linux desktops, see the Setting Up Horizon 7 for Linux Desktops document.
- Connect to a remote desktop for which the Session Collaboration feature is enabled.
You must use the VMware Blast display protocol.
- In the system tray in the remote desktop, click the VMware Horizon Collaboration icon, for example, .
The collaboration icon might look different, depending on the operating system version.
- 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. For Windows remote desktops, 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.
- Select an invitation method.
Not all invitation methods might be available.

After you send an invitation, the VMware Horizon Collaboration icon also appears on the desktop and the Session Collaboration user interface turns into a dashboard that shows the current state of the collaboration session and enables you to take certain actions.
When a session collaborator accepts your invitation to join a Windows remote desktop session, the Session Collaboration feature notifies you and a red dot appears on the VMware Horizon Collaboration icon in the system tray. When a session collaborator accepts your invitation to join a Linux remote desktop session, a notification appears in the primary session desktop.
