I am using mail.com as my email provider.  I can view email on the web by signing into my mail.com account.  All of my email shows up.  I also have MS Office 2011 for Mac and have set up Outlook to receive and sent mail using my @mail.com account.  

The inbox does not alway include incoming mail that I find on the mail.com site.  In fact, email messages sent from Customer Service at Mail.com only show up on their site - not in my Outlook Inbox.  

All of my setting seem to be correct.  I'm perplexed.
