title: Crm 2011 outlook client - Set regarding mandatory
body: <p>Our client is using Microsoft CRM 2011 outlook client and  they have a unique business need. They want to make the "Set Regarding" mandatory for all of their employees using outlook to send emails (Weird huh?).  If a user while sending the email forget to set regarding, outlook should display a notification message and shouldn't let the user send the email.</p>
  
  <p>I have not been able to find any out of the box feature for this so I decided to write an outlook addin. Is there a way to know in outlook addin ItemSend event that the mail item has the value set for regarding field? I can get the subject of the email including CRM:xxxxx but since the email is not yet created in CRM I don't know how to pull the regarding data.</p>
