All, I have a question that I cannot confirm via M$ but have not been able to make it work at all both via MS Exchange and Active Directory Queries. I have a custom address book in the GAL drop down that my companies leadership insists it needs to contain both groups and users. I have explained to them that it will not work from experience, but cannot find the documentation to back me up. In lieu of not finding documentation, I began trying everything I could think, up to including using ADSI Editor to build custom scripts. I began by using Custom Attributes to identify these particular groups and users, but setting the filter rules to pull both a user object and group object yeild a blank preview. Is this possible to filter both users and groups in one search and if so, how do I accomplish this? Rob
