We're running Exchange 2003 with Outlook 2003 clients and use the Ex2003 query based distribution groups extensively. In order to answer the frequent requests from employees, we created a web page on our intranet (running PHP) that does an LDAP query on the fly and displays the current members of any particular query based distribution group. Is is possible in an Exchange 2007/Outlook 2007 environment for someone to view the members of a dynamic distribution group from within their mail client? It is possible to right click on the group name and expand the DL before sending a message? For peace of mind, many people would like to verify who the recipients are before they actually send a message and that is very difficult in an Exchange 2003/Outlook2003 environment. Thanks. Al Truism
