AS3 : cannot fill subject and body in mailto

I am currently programming using as3 and I want to fill subject and body of my mail using mailto.

I tried everything I've seen on Internet but nothing worked :(

This is my entire code:

import flash.display.Sprite; 
import flash.net.URLRequest;
import flash.net.navigateToURL;

function openMailClient(event:MouseEvent):void
{
   var mail:URLRequest = new URLRequest("mailto:hi@hi.com?subject=hi&body=hi");
   navigateToURL(mail);
}
stage.addEventListener(MouseEvent.CLICK, openMailClient);

Can someone help me?

Solution

Based on the comments provided, if your goal is to send an email you should do it in another and better way...

For example you could create a webservice (php script, java service, or other technology dedicated to sending the email, expose an URL which after receiving subject,body, etc will send the mail...)

Regarding your problem with outlook I only found this other Answer that can help you...

mailto: subject= and body= support in email clients

The behavior depends on the browser, OS, and other external factor... The ?subject...&body syntax is not standard and any browser/application treats it in a different way...
