I’m trying to open it like this in outlook with javascript
ex.replace('body','<html><body>');
ex += '</body></html>';
var encodedUri = encodeURI(ex); //encode spaces etc like a url
var a = document.createElement('a'); //make a link in document
var linkText = document.createTextNode("fileLink");
a.appendChild(linkText);
a.href = encodedUri;
a.id = 'fileLink';
a.download = 'download.eml';
a.style = "display:none;"; //hidden link
document.body.appendChild(a);
document.getElementById('fileLink').click();
But it gives me the error

How to solve the doesn’t have a registred handler error?
Or how do i have to write the javascript properly? Or should i handle the eml response differently?
Thanks in advance
