Geolocating a users last Send location (MEC sample)

This is sample one from the where's wally section of my MEC talk and demonstrates how you can locate the geographical place where a user last sent a Message from using EWS, Extended properties and GeoIp.

This script makes use of the x-ms-exchange-organization-originalclientipaddress extended property which is a extended property that gets set on the copy of the message that is saved into the SentItems folder of a mailbox when you send a message from OWA or Outlook (Note this isn't transmitted with the actually messages itself) . eg



 
The value of this property reflects the IP Address of the sending client eg so if your using OWA from a Kiosk PC it will show the IP from the Kiosk, or if your using Outlook from home via Outlook-Anywhere it will contain your ISP's Address. Or if your traveling around the world using different hotspots then the address you will get would be from each of the hotspot's you used. Here's a sample report from a mailbox I used from different hotspot's I was using on my recent trip to MEC which included a short holiday in New York.

To resolve the IP Address to geographical location involves using GeoLocation which has an increasing number of users in IT from WebStats to GeoDNS. In this script I've used Maxmind's GeoLiteCity database and Com object. The only thing with the COM object while it only take a few lines of Powershell to use because its a 32 bit library you need to make sure you run it from 32 bit session of Powershell.

 Before running this code you need the GEOIP database and Com object and the database must be in the following location and named GeoIPCity.dat.


$geoip = New-Object -ComObject "GeoIPCOMEx.GeoIPEx"
$geoip.set_db_path('c:\mec\')

I've put a download of this script here the code itself looks like
