Account expiry dates or account Never expire for all AD users
<p>While I am running the below command getting <code>expiration_date</code> is blank.</p>

<p>Is it possible to get the 'Never expire' instead of blank in <code>expiration_date</code>?</p>

<pre><code>Import-Module ActiveDirectory
$Groups = Get-ADGroup -filter {Name -like "SSL_VPN_Users" } | Select-Object Name
ForEach ($Group in $Groups) {
  Get-ADGroupMember -identity $($group.name) -recursive | 
    Get-ADUser -Properties samaccountname,mail,AccountExpires | 
    select samaccountname,mail,@{l="expiration_date";e={[datetime]::fromfiletime($_.accountexpires)}} | 
    Export-csv -path C:\SSLVPN\SSL_VPN_Users.csv -NoTypeInformation
}
</code></pre>
