I had a previous problems trying to create Query-Based Distribution Groups. I have been able to get most of the groups working properly, however one particular group that I would like to create will not work. I am trying to create a Query-Based Distribution Group for all my network users. I set the values for User, Member of, Is (exactly), Domain Users. However when I test this, I get a message that No Items Match the Current Search. Could someone please tell me if the "Domain Users" Group can be used in Query's, and if so, how can I properly perform this query.
