Overview of this book

PowerShell has become one of the most important skills in an Exchange administrator's armory. PowerShell has proved its mettle so widely that, if you're not already starting to learn PowerShell, then you're falling behind the industry. It isn't difficult to learn PowerShell at all. In fact, if you've ever run commands from a CMD prompt, then you'll be able to start using PowerShell straightaway. This book will walk you through the essentials of PowerShell in Microsoft Exchange Server and make sure you understand its nitty gritty effectively. You will first walk through the core concepts of PowerShell and their applications. This book discusses ways to automate tasks and activities that are performed by Exchange administrators and that otherwise take a lot of manual effort. Microsoft Exchange PowerShell Essentials will provide all the required details for Active Directory, System, and Exchange administrators to help them understand Windows PowerShell and build the required scripts to manage the Exchange Infrastructure.

Writing a basic script

Now that we have covered the basics of Windows PowerShell, let's write our first script. PowerShell uses the .ps1 format to save scripts. Before we get into executing scripts, let's first understand the following PowerShell Script Execution Policies that are in place to prevent unwanted scripts from being executed on your computer.

The cmdlet Set-Execution Policy helps you to change the Policy of which scripts you can run on your computer. There are four different execution policies:

Restricted: In this mode, you cannot run any script and can use Windows PowerShell to run cmdlets in the interactive mode only.
AllSigned: Locally created and those signed by a trusted publisher can be run
RemoteSigned: Scripts downloaded from another computer can run only if these are signed by a trusted publisher
Unrestricted: All the scripts will run regardless of whether they are signed or not

Now, let's set the execution Policy to Remote Signed and verify using Get-Execution Policy cmdlet:

PS C:\> Set-ExecutionPolicy RemoteSigned
PS C:\> Get-ExecutionPolicy

I am going to introduce the PowerShell Integrated Scripting Engine (ISE) that makes it easier to run scripts with features, such as syntax-coloring, tab completion, IntelliSense, visual debugging, and context sensitive Help, as compared to the PowerShell console.

The following script will query the win32_logical disk WMI class. This is a representation of a local storage device on a Windows Computer. There are six possible Drive Types, and we will use a Switch statement to get the output in text describing the type of storage:
