Query Exchange 5.5 users or Groups Problem RRS feed

  • Question

  • Hi All,
    I'm trying to query distribution lists on Exchange 5.5 in C#.

    I have an experience to work to query Users,DLs in AD Windows 2003,but the same code when i ran it against Exchange 5.5 on Windows 2000 no enteries are returned.

    here is my code :

    string strRcptContainer = LDAP://MYSERVERIP;

    //Check to see if the dl is already present

    DirectoryEntry deContainer = new DirectoryEntry(strRcptContainer);

    deContainer.Username = txtUsername.Text;

    deContainer.Password = txtPassword.Text;

    string strFilter = "(objectClass=group)";

    DirectorySearcher dsSearch = new DirectorySearcher(deContainer,strFilter );

    dsSearch.SearchScope = SearchScope.Subtree;

    dsSearch.SizeLimit = 20000;

    dsSearch.PageSize = 1000;

    string[] propToLoadList ={ "name", "ou" };


    SearchResultCollection searchCol = dsSearch.FindAll();

     searchCol.Count  is always Zero ? can any one help to how to fix that ?

    The Same Code is working Perfectly with AD Windows 2003,and since Exchange 5.5 has its own Directory Service,that's why i have to query our Exchange Server to get users or groups.

    Any Help ? ASAP ?
