To allow E911 services for the Media Optimization for Microsoft Teams feature, you must manually enable macOS location services for Horizon Client. These services provide the client's geolocation information to Microsoft Teams running in a remote desktop for location-based routing during emergency calls.
In addition to having macOS location services enabled for Horizon Client, E911 services require certain configurations in the Horizon Agent GPO and on the client system. By default, these configurations are set to allow E911 services but may be changed by an administrator.
Enabling macOS Location Services
To enable macOS location services for Horizon Client, go to System Preferences, select Security & Privacy, click the Privacy tab, and select Location Services. Unlock and use the controls to select Enable Location Services for the VMware Horizon Client app.
E911 Configuration on the Client System
The configure.ini file on the Mac client system includes the html5mmr.webrtc.supportE911 option which enables or deactivates E911 services. By default, this option is set to the value 1 to enable E911 services.
To deactivate E911 services for the client, set the value to 0.
