Sending Outlook Appointments to a Different Server

[jerryc]

Hi.

I'm trying to programmatically send Outlook Meeting announcements to e-mail accounts that use Outlook, but may be on another Exchange server (or, in my case, I am actually on a POP3 server). Is there a way to do this?

This is the CDO code that I'm trying to use, but I do not find a complete example:

class Class1
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main(string[] args)
{
CDO.PersonClass person = new CDO.PersonClass();
String strURL = "mailto:jerryc@vioma.com";
person.Email = "jerryc@vioma.com";

// person.DataSource.Open(strURL,null,0,0,0,"jerryc","");
CDO.IMailbox mailbox = (CDO.IMailbox) person.GetInterface("IMailbox");
CDO.Appointment appt = CreateAppointment(new DateTime(2004,7,15),new
DateTime(2004,7,15),"subject","location","agenda",mailbox);
String[] mandatory = {"jerryc@vioma.com"};
SendMeetingRequest(appt, mailbox, person, mandatory,mandatory);
// Console.WriteLine("URL to inbox for " + strURL + " is: " + mailbox.Inbox);
Console.ReadLine();

}
static CDO.Appointment CreateAppointment(DateTime StartTime,
DateTime EndTime,
String Subject,
String Location,
String TextBody,
CDO.IMailbox iMbx)
{
try
{
// Variables.
CDO.Appointment iAppt = new CDO.Appointment();
// ADODB.Connection Conn = new ADODB.Connection();
// Conn.Provider = "ExOLEDB.DataSource";

//Set the appointment properties.
iAppt.StartTime = StartTime;
iAppt.EndTime = EndTime;
iAppt.Subject = Subject;
iAppt.Location = Location;
iAppt.TextBody = TextBody;

//Save the appointment
/* Conn.Open(iMbx.BaseFolder, "", "", -1);
iAppt.DataSource.SaveToContainer(iMbx.Calendar, Conn,
ADODB.ConnectModeEnum.adModeReadWrite,
ADODB.RecordCreateOptionsEnum.adCreateNonCollection,
ADODB.RecordOpenOptionsEnum.adOpenSource, "", "");

Console.WriteLine("Appointment saved."); */
return iAppt;
}
catch (Exception err)
{
Console.WriteLine(err.ToString());
return null;
}
}

static void SendMeetingRequest(CDO.Appointment iAppt, CDO.IMailbox iMbx, CDO.Person iPers,

Config.Fields.Update();

iAppt.Configuration = Config;

// Add required attendee(s).
long I;
for (I = 0; I < strAttnMandatory.Length; ++I)
{
Console.WriteLine("Mandatory Attendee E-Mail:" + strAttnMandatory[i]);
iAttendee = iAppt.Attendees.Add("");
iAttendee.Address = Convert.ToString(strAttnMandatory[i]);
iAttendee.Role = CDO.CdoAttendeeRoleValues.cdoRequiredParticipant;
}

// Add optional attendee(s).

{
