Recently, I came across with very specific requirement for composing e-mail thru client side code. The requirement was to compose outlook e-mail for daily status report after collecting the data from Project server and SharePoint site. So the outlook 2007 should be pre-installed on the client machine. When a user press the button, the application should pop-up outlook e-mail to let the user makes any changes before sending the mail
I have written the generic code so that it can be used in any such requirement. I hope this will help the developers with the similar requirement.
You need to change the settings of Internet explorer for this to work:
a) Go to ‘Tools’ menu in the internet explorer.
b) Go to ‘Options’.
c) Click “Custom Level” Button.
d) Select the option “Initialize and script ActiveX control not marked as safe for scripting” to Prompt or Enable.
var theApp //Reference to Outlook.Application
var theMailItem //Outlook.mailItem
//Attach Files to the email, Construct the Email including
var subject = sub
var msg = body
//Create a object of Outlook.Application
var theApp = new ActiveXObject("Outlook.Application")
var theMailItem = theApp.CreateItem(0) // value 0 = MailItem
//Bind the variables with the email
theMailItem.to = to
theMailItem.Subject = (subject);
theMailItem.Body = (msg);
//Show the mail before sending for review purpose
//You can directly use the theMailItem.send() function
//if you do not want to show the message.
alert("The following may have cause this error: \n"+
"1. The Outlook express 2007 is not installed on the machine.\n"+

document.write("<a href=\""+"./testemail.asp"+"\""+">"+"Go Back"+"</a>")
Page_Load EventHandler(Note:How onclick attribute is added to button control):
protected void Page_Load(object sender, EventArgs e)
string to, sub, body;
to = "email@example.com";
body = "Body of the mail";
sub = "Subject";
btnSendMail.Attributes.Add("onclick", "SendMail('" + to + "','" + body + "','" + sub + "')");
<asp:Button ID="btnSendMail" runat="server" Text="Send Mail" />
