How to change the UPN in "before user creation"?

Question

I've tried the following script to adapt the UPN to the country, the step will be processed in "before user creation" but the UPN stays default to com:

$propertyName = "countryCode" 
$upnSuffixMap = @{
    "companyName.com" = @("276")
    "companyName.in" = @("356")
    "companyName.cn" = @("156")
    "companyName.com.tr" = @("792")
} 

# Get property value
try
{
    $value = $Context.TargetObject.Get($propertyName)
}
catch
{
    return # Property is empty
}

# Get UPN Suffix
$upnSuffix = $NULL
foreach ($item in $upnSuffixMap.GetEnumerator())
{
    if ($item.Value -notcontains $value)
    {
        continue
    }

    $upnSuffix = $item.Key
    break
}

if ([System.String]::IsNullOrEmpty($upnSuffix))
{
    $Context.LogMessage("UPN suffix was not specified for '$value'. companyName.com will be used.", "Warning")
    return
}

# Get UPN
$userPrincipalName = "%userPrincipalName%"
if ([System.String]::IsNullOrEmpty($userPrincipalName))
{
    $Context.LogMessage("Cannot assign a UPN suffix because the user logon name is empty", "Warning")
    return
}

# Build new UPN
$userPrincipalName = $userPrincipalName.SubString(0, $userPrincipalName.IndexOf("@")) + "@$upnSuffix"

# Save changes
$Context.TargetObject.Put("userPrincipalName", $userPrincipalName)
$Context.TargetObject.SetInfo()

Hello Boris,

The script will not work as the Set-ADUser cmdlet can only be used with existing users. For information on how to achieve the desired, have a look at the following tutorial: https://www.adaxes.com/tutorials_SimplifyingDataEntry_ValidateModifyUserInputWithScript.htm.
