Hello,
In AD we have a password expiration policy set for 14 day notification however users don't always get this on the domain and we have some users on the Cisco VPN.  I'd like to know if anyone has a reliable script they are using that would email users of upcoming password expiration they'd be willing to share.
Thanks!

Try this:

Add-PSSnapin Quest.ActiveRoles.ADManagement

$ExpiringPasswords = Get-QADUser -SearchRoot "OU=Faculty,DC=Test,DC=local" -PasswordNotChangedFor 85 | Where PasswordNeverExpires -eq $False | Select-Object email -Unique

$emailFrom = 
$subject = "Password will Expire Soon"
$smtpServer = 

Foreach ($ExpiringPassword in $ExpiringPasswords) {

$emailto = $ExpiringPassword.Email
$body = "From the Glynn County I.T. Department: <br /><br /> You are receiving this email because your password expires within 5 days. While on site, press CTRL + ALT + DELETE to change your password. Your password must be 10 characters long and can contain special characters/spaces. It cannot be a previous password. <br /><br /> If you have any problems changing your password, please see your media specialist or technician. You will never be asked for your password by the Glynn County I.T. Department. If you receive an email requesting your password, please contact your media specialist or technician."

Send-MailMessage -to $emailto -from $emailFrom -Subject $subject -Body $body -BodyAsHtml -SmtpServer $smtpServer
}

It uses the quest AD powershell cmdlets. You will also need to specify the search root in line 3, and set line 5,7

I left our email body (line 12) in there for you to use as a template. We also let our users reset their password through a (free) self service tool:

Thank you this looks awesome I will give it a test.
Are you running this as a scheduled task on the domain controller or how often are you running?

@jmoody10 - If I have a test OU I want to run it against before production does this look right:
"OU=testou,DC=northamerica,DC=bergquistcompany,DC=com"
I also set the following as noted:
$emailFrom = "securityadmin@bergquistcompany.com"
$subject = "Password will Expire Soon"
$smtpServer = "mail.bergquistcompany.com"
and I appreciate the body to use as a template.  To confirm how often do you run it and do you have it as a .ps1 that you are running through scheduled tasks?  Does it look like C:\powershell.exe -password.ps1

@Sandeshdubey - to confirm I only need to set these between the "#" to establish the variable is that correct:
$smtpServer="wilma.northamerica.bergquistcompany.com"
$from = "bergquistadministrator@bergquistcompany.com"
$expireindays = 14
Then is this also being run from a task?  I'm on 2012 and to start a program/script would I enter Powershell as the program and the .ps1 as an argument or just the .ps1 as the script?

@ Sandeshdubey

I have downloaded the first script set
$smtpServer="wilma.northamerica.bergquistcompany.com"
$from = "kristinebollinger@bergquistcompany.com"
$expireindays = 14

and run it from powershell .\password change notification.ps1 and it runs fine but no email ever comes through.  Are you using this?  I've tried 2012 and 2008

There are lots of these types of scripts out there, they assume you have the email AD attributes filled in properly:

5. Subject says "Your password will expire in   days!" but there is no number of days
 

Any help would be appreciated!
