Thank you for the example... However it isn't working. This is the code that I am using. It'll say it changes it, but when I view it in AD, it's still blank.

Code:

$UserObj = GetObject("LDAP://ou=Employees,ou=Users,ou=Location,dc=Company,dc=com") 
$UserObj.Filter = Split('user')

For Each $User in $UserObj
	$Address = Lcase($User.sAMAccountName) + "@@mycompany.com"
	? 'Current address is: ' + $User.Get("mail")
	$User.put("mail",$Address)
	$User.setinfo
	? 'E-mail address is now set to: ' + $User.Get("mail")
Next 

Sleep 10


Do I have to run it with elevated permissions?

HELP!!!!
