Archived items icon remains unchanged in Inbox

Hi,

All users in our organization are using Enterprise Vault 9.0 Plugin for Outlook 2010.

One of the users is facing a peculiar problem.

Messages that are archived are showing up in normal Outlook Envelop icon instead of the Vault icon.

Another problem is that the archived mails for the same user are getting downloaded as msg files instead of getting displayed as normal Outlook forms.

Has anybody faced a similar issue before? 

I googled for the issue and found some discussions where increasing font DPI settings caused the issue and reverting back to normal DPI fixed it.But here the font size is normal 96 dpi. Also the issue was reported for Outlook 2007 and in our case we are using Outlook 2010.
