Answer 1

You can use the OnPremiseDistinguishedName extension property.

Example:-

    foreach($line in Get-Content c:\users\myuser\users.txt) {
    if($line -match $regex){
        $onPremisesDistinguishedName = (Get-AzureADUserExtension -ObjectId $line).get_item("onPremisesDistinguishedName")
        $domain = $onPremisesDistinguishedName.split(",")
        $alias = $line.Split("@")
        $sAMAccountName = ($domain[2]).Substring(3)
        $sAMAccountName + "\" + $alias[0]
    }
}
