sending event email

[ccMcBride]

my smtp settings (this works with all other emails)

Code:

      SMTP.Host := cdsDefaultSettings.FieldByName('SERVERNAME').AsString;
      SMTP.Username := cdsDefaultSettings.FieldByName('USERNAME').AsString;
      if cdsDefaultSettings.FieldByName('Enable_ssl').AsBoolean then
      begin
         SMTP.AuthType := satDefault;
         SMTP.Password := DecryptStr(cdsDefaultSettingsACCOUNT_ID.AsInteger);
      end
      else
         SMTP.AuthType := satNone;
      if (not IsNullStr(cdsDefaultSettings.FieldByName('PORT').AsString)) and
         (cdsDefaultSettings.FieldByName('PORT').AsInteger <> 0) then
         SMTP.Port := cdsDefaultSettings.FieldByName('PORT').AsInteger
      else
         SMTP.Port := 25;
      if cdsDefaultSettings.FieldByName('flags').AsInteger <> 0 then
      begin
         IOHandler.Host := SMTP.host;
         IOHandler.Port := SMTP.Port;
         if cdsDefaultSettings.FieldByName('flags').AsInteger = 4 then
            ioHandler.sslOptions.method := sslvTLSv1_2
         else
            ioHandler.SSLOptions.Method := TIDSSLVersion(cdsDefaultSettings.FieldByName('flags').AsInteger - 1);
         SMTP.IOHandler := ioHandler;
         if cdsDefaultSettings.FieldbyName('flags').AsInteger = 4 then
            SMTP.UseTLS := utUseExplicitTLS;
      end
      else
      begin
         SMTP.ioHandler := nil;
         SMTP.UseTLS := utNoTLSSupport;
      end;
//   end;


   emMessage.From.Address := cdsDefaultSettings.fieldByName('username').AsString;
   if not isNullStr(cdsDefaultSettings.fieldByname('display_name').AsString) then
      emMessage.From.Name := cdsDefaultSettings.FieldbyName('display_name').AsString
   else
      emMessage.From.Name := globalConnection.LoginRec.LoginName;
   if cdsuserEmail.IsEmpty then
      emMessage.ReplyTo.EMailAddresses := cdsDefaultSettings.fieldByName('username').AsString
   else
      emMessage.ReplyTo.EMailAddresses := cdsUserEmail.fieldByName('email_prime').AsString;
   emMessage.From.Address := emMessage.ReplyTo.EmailAddresses;

I changed the main message part to multipart/mixed, still error.
as test, I also did the following:
(1)

Code:

      dmEmail.emMessage.ContentType := 'text/calendar;method=PUBLISH';
      dmEmail.emmessage.Body.Text := eventText.Text;

//      with tIDText.Create(dmEMail.emMessage.Messageparts) do
//      begin
//         ContentType := 'text/calendar;method=PUBLISH';
//         Body.Text := eventText.Text;
//      end;
//      with TIdAttachmentFile.Create(dmEmail.emMessage.MessageParts, fName) do
//      begin
//         ContentDisposition := 'inline';
//         ContentType := 'text/calendar;method=REQUEST';
//         ExtraHeaders.Values['Content-ID'] := ExtractFileName(fName);
//         ContentID := ExtractFileName(fName);
//         Filename := ExtractFilename(fName);
////           parentPart := 1;
//      end

it was sent with no errors, the event was attached as an ICS file, no 'accept/decline' on email

So, 'something' is missing specifically when I'm sending it with a request method.  just not sure what.

---

after more banging my head against my desk, I tracked this down to using outlook 365 as my email server.
if I use my gmail account for outgoing email, it works just fine (the email has the accept/tentative/decline buttons when sent to my outlook account).


any further ideas?
