[Evolution] evolution-ews not showing new mail

[Joseph Ervin <gm4jervin gmail com>]

Hi folks,

I've no idea how this happened, but yesterday evolution stopped showing new mail.  The odd thing is that when a message arrives, I get the gnome notification of the arrival of the mail, but it won't show up in my inbox.  Here's the odd part.....if I log into my exchange account directly over the web and *read* the new mail, then it magically shows up in the evolution inbox. 

Is there some setting that I've inadvertently turned on to *not* show unread new mail? 

Sincerely,

Joe
