I am unable to drag and drop email attachments into Outlook 2011 emails from an Outlook search screen.

If I run a search in Outlook Mac 2011, I am unable to drag any of the search result emails into an email I am drafting, All I get is an attempt to highlight multiple search results.  I am able to drag and drop from my Outlook mail folder (i.e., when I am not displaying search results).  This wouldn't be so bad if Outlook would allow me to "copy" one of the emails in my search results, but it won't.  Instead, I have to remember the date and folder in which the target email resides, go to that folder, and drag and drop it from there.  A real pain if you are trying to drag and drop multiple emails as attachments.  Help?
