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.

Writing a basic script

As we have seen in the In-Place hold section, the Recoverable Items folder has its own storage quota and has Deletions, Versions, Purges, Audits, Discovery Holds, and Calendar Logging as subfolders. This script will loop through the mailboxes and export the size of these subfolders to a CSV file.

The $Output is an empty array used later to store the output of the script. The $Mbx array stores the list of mailboxes. We then use Foreach to loop through the mailboxes in $Mbx. Note the usage of two if-else statements for the Audits and Discovery Holds section in the script, which are present to ensure that we don't get errors if the user is not enabled for Mailbox Auditing and In-Place holds respectively.

We have created a new object to create a new instance of a PowerShell object and used the Add-Member cmdlet custom Properties to that object and store it in the $report variable for each mailbox in the list. The results are then added to the $Output array defined earlier...
