How can I simulate with SimKey sending an email?

I am trying to send an email in Outlook and I get the message "A program is trying to send an email on your behalf", so this email cannot be automatically sent.

That's why I tried to simulate pressing the keys CTRL+ENTER in outlook, which means "send", but it's not working. Any idea? Thanks in advance.

This is the code:

function sendolmail(to,subject,body)

%Sends email using MS Outlook. The format of the function is

%Similar to the SENDMAIL command.

% Create object and set parameters.

h = actxserver('outlook.Application');

mail = h.CreateItem('olMail');

mail.Subject = subject;

mail.To = to;

mail.BodyFormat = 'olFormatHTML';

mail.HTMLBody = body;

% Send message and release object.

mail.Display;

import java.awt.Robot;

import java.awt.event.*;

SimKey=Robot;

mail.Display;

pause(3)

SimKey.keyPress(KeyEvent.VK_CONTROL);

SimKey.keyPress(KeyEvent.VK_ENTER);

SimKey.keyRelease(KeyEvent.VK_CONTROL);

SimKey.keyRelease(KeyEvent.VK_ENTER);

% mail.Send; %This works but asks me to allow another program to send the email

h.release;

end
