Modify multiple Active Directory Accounts with PowerShell

Has you company recently moved to a new location? If so here is a script to modify the "StreetAddress" Active Directory attribute for multiple users at once.

Import-Module ActiveDirectory
 $users = $i = $null
 $users = Get-ADUser -filter * -property StreetAddress
 ForEach($user in $users)
  {
   if([string]::isNullOrEmpty($user.StreetAddress))
    {  
      "modifying $($user.name)"
      Set-ADUser -Identity $user.distinguishedName -StreetAddress "1600 Pennsylvania Ave NW"
      $i++
    }  
 }  

This could be used to modify any of the Active Directory attributes by simply editing the -property being queried.
