[Evolution] strange Evolution view problem

[Arnold Wang <arnold wang inovis com>]

I'm running Evolution 2.10.3 which comes with Fedora 7. It is connected to a MS Exchange 2003 server through the connector. It works in general. 
I start to notice a strange problem recently, whenever I send myself a message from the same account, it won't show up in the inbox. When I checked from the Outlook client, the message was there. I have tried disable all  filters, unchecked the "check incoming mail for junk" option. Nothing helped.
What can possibly be the problem? How to trouble shooting and fix it?
Thanks.
