Update Lync Client Location with IP GeoLocation

I regularly bounce around on different networks and vpn connections. I got tired of manually setting the location in Lync and found myself just ignoring it altogether. After doing some poking around, I decided to throw a powershell script together to just do the dirty work for me.

The script uses Telize for geoip data and DNSOMatic Telize for the external IP. The script requires the Microsoft.Lync.Model.dll from the Lync 2013 SDK (15.0.4603.1000 as of this post). You can find the Lync Client 2013 SDK here.

You can then add an event trigger to fire off the script when you connect to a network: On an event; On event - Log: Microsoft-Windows-NetworkProfile/Operational, Source: Microsoft-Windows-NetworkProfile, vent ID: 10000

Note: I adjusted my personal version to detect when I’m on my company’s network so it won’t interfere with Lync setting to location for our office. Always test and understand the ramifications if using in a production environment.

Gist on Github: Update-LyncLocation.ps1

#requires –Version 3.0
<#
.SYNOPSIS 
Updates Lync 2013 Client's location information with geolocation data based on internet ip address.

.DESCRIPTION
The Update-LyncLocation.ps1 script updates the Lync 2013 Client's location information. It uses the 
Telize web service to determine your external ip address and then queries Telize to collect publicly 
available geolocation information to determine your location. That data is then parsed into usable 
information and published to the Lync client.

****Requires Lync 2013 SDK.**** The SDK install requires Visual Studio 2010 SP1. To avoid installing 
Visual Studio, download the SDK, use 7-zip to extract the files from the install, and install the MSI 
relevant to your Lync Client build (x86/x64).

.INPUTS
None. You cannot pipe objects to Update-LyncLocation.ps1.

.OUTPUTS
None. Update-LyncLocation.ps1 does not generate any output.
