How to exclude Group members and its sub group members of a group in powershell?

Hi All,

I would like to export all users from my domain except the members of particular group members and its sub group members. Below is the script I used, but It worked for the primary group but it dinot worked for sub groups .

Get-ADUser -Filter * -Properties memberof | ? {(($_.memberof | Out-String) -notmatch 'ServiceAccounts')} | Select-Object -Property samaccountname

Please Help
