Just last week, I had the privilege of presenting at Microsoft Ignite 2015. The topic of my presentation was how to deploy and configure Exchange 2013 using DSC. Specifically, I talked about how to perform the Exchange specific phases of an end to end Exchange deployment, including automating Jetstress, installing Exchange, and performing server, DAG, database, and mount point configuration. I also talked about some lessons learned while using DSC to deploy and configure Exchange in a large scale environment for one of my customers.
