Am trying to send email using MS Outlook API through from my .Net 4 C# application on a Windows 7 machine. Am able to send it successfully if I dont set any senders email Id in the code.

But when I invoke SendUsingAccount(), I get an access violation error:
<blockquote style="margin-bottom:10px; padding-bottom:1px; border-right-width:0px; border-bottom-width:0px; border-left-width:0px; border-style:initial; border-color:initial; font-size:14px; vertical-align:baseline; background-color:#ffffff; quotes:none; font-family:Arial,Liberation Sans,DejaVu Sans,sans-serif; text-align:left
