Professional Windows® PowerShell for Exchange Server 2007 Service Pack 1

Part IV: Automating Administration

The first line of the script adds the Exchange snap - in. If you run a PowerShell script from the command

line you don ’ t get the Exchange management snap - in, so you need to add it manually. The second line of

the script grabs the parameter that is passed to the script on the command line. The

$args special

variable is an array of the arguments that were passed to the script on the command line. The first item

in the array is the first parameter specified on the command line. The following example uses a single

argument in the script to specify the file to open and parse the contents of it so that you can determine

which mailbox stores the script needs to modify:

Add-PSSnapin *Exchange* | out-null

$MBItems = get-content -path $args[0]

You use the Get-Content cmdlet to open the filename that you passed on the command line. Next, for

each line read in from the file, you are going to run a

Set-MailboxDatabase cmdlet to set the defaults

that have been defined for your Exchange users. For a detailed discussion of the

Set-MailboxDatabase

cmdlet please reference Chapter 8 . You will want to construct a

Set-MailboxDatabase command that

sets all relevant settings to meet your standard.
