I've run into many situations where we've needed to email end users of their pending password expiration. Sometimes it's remote users who don't see the password change alerts, sometimes it's just a way to show that the end user was notified their password was expiring. Here's the script I've cobbled together from various sources. It emails their password once it's 7 days out. I usually schedule the script to run daily at noon.
# Please Configure the following variables....
$smtpServer="smtp.domain.com"
$expireindays = 7
$from = "noreply@domain.com"
$logging = "Enabled" # Set to Disabled to Disable Logging
$logFile = "c:\logs\pwdemaillog.csv" # ie. c:\logs\pwdemaillog.csv
#$testing = "Enabled" # Set to Disabled to Email Users
$testRecipient = "adminuser@domain.com"
$date = Get-Date -format ddMMyyyy
