Powershell Script to Send Password expiry notification to users


I am looking for a good script to send a password change notification users whose password is expiring in less than 15 days time. Hope somebody can use below script.


# PowerShell script to gather Password expiry date for all users and —
# send e-mail notification to user with Password expiry date less than 15 Days
# Created by Vipin Vasudevan

# Set the target OU that will be searched for user accounts
$objuser= $null
$objou= [ADSI]”LDAP://$OUDNPATH”
$searchad= [System.DirectoryServices.DirectorySearcher]$objou

# LDAP Filter for searching user account
$searchad.Filter =”(&(objectcategory=person)(objectclass=user)(!useraccountcontrol=514))”
$searchad.PageSize= 1000
$searchad.searchscope= “Subtree”

# Fill in the user variables
$objusers = $searchad.findall()

# Take each users to calculate las passowrd reset time and Expire date
foreach ($evuser in $objusers)
# Calculating the Last password reset date
$lastpwdchng = $($evuser.properties.pwdlastset[0])

# Convert the ‘pwdlastset’ NT system time into a readable format
$lastpwdchng = [datetime]::fromfiletime($lastpwdchng)

# Enumerate “Name, Mail and Samaccountname” attribute value for each users
$name = $($evuser.properties.name)
$mail = $($evuser.properties.mail)
$sam = $($evuser.properties.samaccountname)

# Convert SAMaccountName to UserprincipalName
$upn = $sam + “@DOMAIN.com”

# Define the default password age ( maximumPasswordAge ) and get current date to ‘$today’
$policy = 45
$today = Get-Date

# Identify the current password age to ‘$daystoexpiry’
$daystoexpiry = ($today – $lastpwdchng).Days

# Identify the days remaining to expire password checking password age with default password age.
$balance = $policy – $daystoexpiry

# Identify Date and time passsword is going to expire by adding 45 days to Last password set date.
$expireyday= $lastpwdchng.Adddays(45)

# Check users that have a password expiring in 15 days or less
If ($balance -lt 15 -and $balance -gt 0)
# E-mail structure with message body

$WarnMsg = ”
