Outlook 2007 Junk Email turned off but still working

[Jeannie]

I have Tools-Options-No Auto Filtering set. I have one email that gets
posted to junk email. If I try to do a reply or forward, using this email,
it goes to junk email. But only one email from this person. All other emails
from this person go to the Inbox. And no other emails from anyone else are
affected.

I have also emptied out the Blocked Sender List. I do have items in the
Safe Sender/Recipients, but don't think this is a problem.

Thanks for your help
