Hopefully you managed to get yourself started with client certificates in the last post, or maybe this was something you had already sorted out in your own lab without any assistance of mine. The thing is, an ActiveSync configuration that only works over the LAN isn’t all that worthwhile is it? You’ll want to make it work across them Intertubes as well don’t you?

Following up my previous article that configured Exchange for using client certificates, this time enabling it over the WAN as well with the help of ForeFront TMG 2010.
Certificates is not only a recurring theme on this site, it’s also a recurring pain point from what I hear. Getting it working is just down right confusing sometimes. With this in mind I thought I’d walk us through a scenario where you want to secure your Exchange ActiveSync deployment with the use of client certificates.

How to configure Exchange for client certificates while accessing ActiveSync over the LAN.
I got my hands dirty with ActiveSync two weeks back (http://mobilitydojo.net/2010/03/17/digging-into-the-exchange-activesync-protocol), and shared the results with you here. I also mentioned that doing the things I did required a few lines of code since not everything could be done in Fiddler. Because of this I promised you I had something in the works to let you actually play around too, without cracking open your Visual Studio, and now I’m trying to make good on this promise 
I introduce to you, the first beta release of “Exchange ActiveSync MD”. It is a desktop app that will let you emulate a device connecting to ActiveSync. Yes, it is similar to what www.testexchangeconnectivity.com, but I only focus on EAS, and I have a couple of options not present in the ActiveSync test MSFT provide. It will require you to have .Net 3.5 installed on your computer – I’ve tested it running on Windows 7 and Windows Server 2008 R2, but it should work on other Windows versions too with .Net present. It will not require an installation, and you can just run the .exe file itself.
