Install Mobility Service and Autodiscover Service


Topic Last Modified: 2012-10-13

You need to run the Mobility and Autodiscover Services installer on each Front End Server and each Director in every Lync Server pool where you want to provide the mobility feature. The installer installs the Mobility Service on Front End Servers and installs the Autodiscover Service on Front End Servers and Directors.

The latest installation package is available for download from the Microsoft Download Center at

The default configuration enables Mobility Service traffic to go through the external site. However, you can restrict Mobility Service traffic to the internal corporate network. When you restrict the traffic to the internal corporate network, users cannot access mobility services from outside the corporate network.


When you restrict mobility traffic to the internal network, you should configure the internal Web Services virtual IPs (VIPs) for cookie-based persistence on your hardware load balancer. For details, see Load Balancing Requirements.
