Unable to add members with in a distribution list programmitically in Office 365 RRS feed

  • Question

  • Hi All,

    I am developing an application with visual studio, to create a new distribution list and then add members in this list. with the below code I am able to create the distribution list, but it is not adding the members in the list. Please note that I am adding the existing members (already in contact) in this list. Please have a look in the below code :

    using (Runspace runspace = RunspaceFactory.CreateRunspace(connectionInfo))
                    using (PowerShell powershell = PowerShell.Create())

                        powershell.Runspace = runspace;
                        Command cmd = new Command("New-DistributionGroup");
                        cmd.Parameters.Add("Name", "Managers1");
                        cmd.Parameters.Add("MemberJoinRestriction", "Open");

                        cmd = new Command("Add-DistributionGroupMember");
                        cmd.Parameters.Add("Identity", "Managers1");
                        cmd.Parameters.Add("Member", "vinayshakti@yahoo.co.in");

                        //Invoke the command and store the results in a PSObject collection
                        Collection<PSObject> results = powershell.Invoke();
                        //Iterate through the results and write the DisplayName and PrimarySMTP
                        //address for each mailbox
                        foreach (PSObject result in results)
                            //Console.WriteLine(string.Format("Name: {0}, PrimarySmtpAddress: {1}", result.Properties["DisplayName"].Value.ToString(), result.Properties["PrimarySmtpAddress"].Value.ToString()));


    the above code is not giving me any exception however it is also not adding members with in the group.

    I have also post this problem here : https://community.office365.com/en-us/f/172/t/404411

    please  help me and let me know why is it not adding the member in the above created group.

  • Your trying to add an external email address to a distribution list which would only be permitted if the Email Address was associate with an Mail Contact https://technet.microsoft.com/en-us/library/bb124519(v=exchg.150).aspx

    Also you don't need to use Add-DistributionGroupMember in your example because New-DistributionGroup has a members parameter all you need is to specify the members you want in the list your creating. eg

                    Command newDG = new Command("New-DistributionGroup");
                    newDG.Parameters.Add(new CommandParameter("Name", "Test-DL"));
                    newDG.Parameters.Add(new CommandParameter("Members", new String[]{"glen@domain.com","fred@domain.com"}));
