I have an email in my inbox.  If I scroll through the inbox view I can see it.  But if I click in the Search This Folder window, and key in "from:term-goes-here", without the quotation marks and with a part of the email address I'm seeking in place of term-goes-here, Outlook doesn't find the email entry.  This should be stone simple - I have an email with the from address being "*** Email address is removed for privacy ***", enter the search term as "from"claudia" and Outlook can't find it.
