Therefore it is directed to the Out-Null cmdlet
via pipeline. All default output from New-Mailbox is basically ??? thrown away. ???
# Create the mailbox enabled accounts
foreach ($user in $users)
{
New-Mailbox -Name:$user.name -Database:$user.Database `
-OrganizationalUnit:$user.OrganizationalUnit `
-UserPrincipalName:$user.UserPrincipalName `
-FirstName:$user.FirstName -LastName:$user.LastName `
-Password:$password -ResetPasswordOnNextLogon:$true `
-ErrorVariable err | out-null
After each execution of New-Mailbox , an if statement is used to test if $err is holding a value not equal
to null. If New-Mailbox encountered no errors during execution, the value of $err should still be set to
null. If there was an error during execution, $err holds an error message corresponding to the error that
was encountered. If an error was encountered the conditional test evaluates as true and the code block is
executed.
The $errorString variable is used to store a text message string that includes the name of the user
( $user.name ) that was being processed when the error occurred. The string includes the keyword
[ERROR] to make it easier to search the log file when looking for errors. Note that this is an arbitrary
word and not a specific Windows PowerShell keyword.
