Re-introduced in Exchange 2013 SP1 is Command Logging. This was available in Exchange Server 2010 when using the Exchange Management Console. This way you could easily see what commands the Management Console was actually executing.
Command logging is now also available in Exchange Server 2013 SP1, but you have to be aware that you need to turn it on before you start working in the Exchange Admin Center. In EAC click on the little arrow in the top right corner and select the Show Command Logging option.
A new window appears where all commands are shown based on what you configure in EAC. It can be a bit cryptic, sometimes object GUIDs are used instead of normal (readable) names but at least it’s possible to figure out what’s happening under the hood.
In the screenshot shown here I’ve created a new Email Address Policy and I can use Command Logging to figure out what EMS commands were used. The only thing I have to figure out now what container is used for the User objects, but that’s not too difficult.
