I need to recover a lost draft message

A message in my drafts folder went missing this morning.  I believe what happened is that my laptop restarted (i.e. crashed) while the draft message was open for edit, though I was away from my laptop when this happened.  When I logged back into Outlook.com the message was not in my drafts folder, not in my deleted folder, and was not recovered into my deleted folder using the "recover deleted messages" link in the deleted folder.  In short the message seems to have vanished?  The message had been in my drafts folder for a while and I had made a number of incremental edits to this file fairly recently.  The file was there this morning (Aug 7, 2013).   Is there any way to restore this file to my drafts folder from a server backup?
