    Yesterday night,I downloaded and installed IE6,and it's english version.
When I opened Outlook,I found it's language had been changed to english(it
used to be Chinese),the mere,the asset about Outlook never changed,including
mail accout and news group.
    How can I get back the outlook like before.
