Open Outlook from WPF Application

Question

what I am trying to do is I have a label and MouseLeftButtonDown Event on it when the user click on the label it open the outlook application but whenever click again it run into an Exception here is the code that I have `

if (e.LeftButton == MouseButtonState.Pressed)
{
    Microsoft.Office.Interop.Outlook.Application objOutlook = new Microsoft.Office.Interop.Outlook.Application();
    Microsoft.Office.Interop.Outlook.MailItem mic = objOutlook.CreateItem (Microsoft.Office.Interop.Outlook.OlItemType.olMailItem) as Microsoft.Office.Interop.Outlook.MailItem;
    mic.To = "someone@live.com";
    mic.Subject = "l";
    mic.Body = "h";
    mic.Display(true);
}

and here is the Exception that I got ![Com Exception][1]

[1]:

I put it as someone@live.com for privacy but, when I need to run the program I change it back to my support E-mail — Dexter90, Sep 30 '14 at 06:16
Google for "outlook interop rpc_e_call_rejected" gives many results, e.g. [this](http://blogs.msdn.com/b/akashb/archive/2008/11/03/unable-to-instantiate-outlook-object-from-visual-studio-2008-on-vista-with-uac-on.aspx). What have you tried? — cremor, Sep 30 '14 at 07:03

How about that

var url = "mailto:foo@bar.com?subject=Test&body=Hello";
System.Diagnostics.Process.Start(url);

I forgot to mention that this will just open your default browser, not particularly Outlook. – coder0815 Sep 30 '14 at 10:44
Much better to open the default browser because maybe some users dont like to use outlook thank you – Dexter90 Sep 30 '14 at 11:05
Do you know how I could change this to also include an attachment file? I've tried &attachment=" + filepath – Ralt Nov 17 '14 at 14:29
@coder0815 : What if the `subject` or `body` contains the string `&`? – A Coder Jun 22 '16 at 09:26
