Get the distribution list owner from Active Directory

Hi,

How can I get the owner of the Outlook  distribution list? I've already get all the members of the a given mail group thru DirectorySearcher but there is no owner property available in DirectoryEntry Class. Can I use the Microsoft.Office.Interop.Outlook COM obj to get the owner of the group (group name that I retrieve from DirectorySearcher)?  Please advise.

Thanks.
