Question about Outlook Express

I have Outlook 2011 for Mac, version 14.2.3.  My problem seems to have been created by myself. Plus, there are no answer out there specific to my problem.  I accidentally tried to send a 124mb attachement.  Well it never made it out of my outbox. It was turned into to a draft email and resided in my local computer in the Drafts mailbox.  Seeing in my Drafts Box I deleted the email.  Well, now my email is trying to push it to my Deleted Box on Exchange server. It fails of course.  And my email tries to send it about every minute or so. No as that service kicks in my email hangs or gets stuck.  I notice this in the progress window.  That deleted email is no where to found.
