title: How to get the Outlook mail item's size?
body: <p>'m writing an Outlook Add-in for Outlook 2007. This is a VSTO 3.0 , C# add-in. I capture the send event in the add-in and then check some of the Email properties (Which is being sent out) and based on that display some alert.</p>
  
  <p>When I try to get the total size of email using mailItem.Size, it always returns 0 while the actual size of email is not 0. And if I save the email (mailitem.Save()) then mailItem.Size returns the correct size of the mail.
  Does any one know about reason behind this behavior . Is there any otherway to get the email size ?</p>
