Microsoft Exchange Server PowerShell Essentials

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.

However, if you use the same cmdlet in Exchange 2010/2013/2016 without the -Database parameter, a built-in cmdlet extension agent called Mailbox Resources Management is invoked.

One thing to note here is that the cmdlet extension agents can be invoked by the Exchange 2010/2013/2016 cmdlets only. Exchange 2007 or any third-party products cannot invoke these agents. Also these agents cannot be invoked through scripts. But if the scripts contain...
