PowerShell: Create Numerous Test Mailboxes

A developer in one the departments I support requested 50 test mailboxes. Below is the PowerShell script I ran to quickly take care of the task.

# AD Setting for Multi Domain Forest
Set-ADServerSettings -ViewEntireForest $true

$password = ConvertTo-SecureString -String 'CreativeThoughtGoesHere2011$' -AsPlainText -Force

for ($i=1; $i -le 50; $i++)
{
$un = "AppTestAccount" + $i
$upn = $un + "@mydomain.edu"
New-Mailbox -UserPrincipalName $upn -Alias $un -Database "EX-MDB-001" -Name $un -OrganizationalUnit "OU=RESOURCEACCOUNTS,DC=MYDOMAIN,DC=EDU" -Password $password -DisplayName $un -ResetPasswordOnNextLogon $false

}
