Enable user for Lync if not already

Experts,

This should be relatively simple, but I'm drawing a blank from my searches.  If possible, can someone point me in the right direction on how to handle PS negative returns?

This is in regards to Lync, where I need to execute the following:

Enable-CSUser –identity “sAMAccountName” –RegistrarPool “SpecifiedPool” –sipAddressType EmailAddress

But, I need to add it in the "fail" portion of "Get-CSUser".  Basically, if a user isn't enabled, to go ahead and do it.

Thanks for any assistance that can be provided.  Apologies for the basic question, I've searched quite a bit for this, but keep coming back empty.

Try the following...

You will need to run this from the Lync Powershell Management Console. While also importing the Active Directory Module. 
Import-module activedirectory
$FindUsers = Get-ADUser -Filter * -Properties name, samaccountname, msRTCSIP-PrimaryUserAddress
if ($User.msRTCSIP-PrimaryUserAddress -eq $null) {
Enable-CSUser -Identity $User.samaccountname –RegistrarPool “SpecifiedPool” –sipAddressType EmailAddress
} else {
Write-Output "$User is already Lync Enabled"
}
