title: Get the Outlook Mail Count by Sender Name
body: <p>I am developing an Outlook 2007 Add-in in C#, where I need to count the number oif mails a particular sender has sent ? </p>
  
  <p>For example, person A has sent 5 mails, person B has sent 10 mails &amp; person C has sent 15 Mails. How can I get this count for every member ? </p>
  
  <p>I can write this logic of my own as well using a <code>Dictionary&lt;String, Int32&gt;</code>, but when this sender list becomes big, It will be a HUGE performance hit.
  Is there any predefined property for this?</p>
  
  <p>Thanks in Advance.</p>
