Powershell script + SMTP server does not work properly

Question

WARNING! There was an error parsing the document

Hello,

I have the following script that I found online with my personal modification. I have basic skills in powershell so I'm not a master. The goal is to send an email to the user as soon as he hits a 14-day countdown until having his password expired. It will give them enough time to reset it before the radius VPN stop working. The rest of the script is working properly. Like the part that sends an email to the supervisor. I would need your help to fix the part that is supposed to send the email to the user. I hid personals information for security purposes. Some parts are in French since it’s my first language.

Thanks for your help!

Hello there,

Instead of troubleshooitng your code can you try the below script and see if that helps.

Use the following PowerShell script to check user password expiration dates and send an expiry notification email seven days in advance:

#Import AD Module
 Import-Module ActiveDirectory
 
#Create warning dates for future password expiration
$SevenDayWarnDate = (get-date).adddays(7).ToLongDateString()

#Email Variables
$MailSender = " Password AutoBot <emailaddress@somecompany.com>"
$Subject = 'FYI - Your account password will expire soon'
$EmailStub1 = 'I am a bot and performed this action automatically. I am here to inform you that the password for'
$EmailStub2 = 'will expire in'
$EmailStub3 = 'days on'
$EmailStub4 = '. Please contact the help desk if you need assistance changing your password. DO NOT REPLY TO THIS EMAIL.'
$SMTPServer = 'smtp.somecompany.com'
 
#Find accounts that are enabled and have expiring passwords
$users = Get-ADUser -filter {Enabled -eq $True -and PasswordNeverExpires -eq $False -and PasswordLastSet -gt 0 } `
 -Properties "Name", "EmailAddress", "msDS-UserPasswordExpiryTimeComputed" | Select-Object -Property "Name", "EmailAddress", `
 @{Name = "PasswordExpiry"; Expression = {[datetime]::FromFileTime($_."msDS-UserPasswordExpiryTimeComputed").tolongdatestring() }}
 
#check password expiration date and send email on match
foreach ($user in $users) {
     if ($user.PasswordExpiry -eq $SevenDayWarnDate) {
         $days = 7
         $EmailBody = $EmailStub1, $user.name, $EmailStub2, $days, $EmailStub3, $SevenDayWarnDate, $EmailStub4 -join ' '
 
         Send-MailMessage -To $user.EmailAddress -From $MailSender -SmtpServer $SMTPServer -Subject $Subject -Body $EmailBody
     }
    else {}
 }


Hope this resolves your Query !!
