Running Windows 7 Home Premium.  Two questions in order of importance:

1.  I opened WLM and saw a new email I wanted to read right away.  It was second in the queue.  I deleted the first email and both the first and the second disappeared.  The first email is in my deleted folder.  The second email is nowhere to be found -- not in the Inbox or Deleted Box or Trash or Junk.  I've searched everywhere.  How do I recover it, if possible?

2.  When I download new emails, why does the computer search every single folder in my Inbox and how do I change that?

THANK YOU!
