How can i configure stub icons for lotus notes mailboxes.

I recently installed Domino Mailbox Archiver Agent and in order to view the stub icon for the message archived on the Lotus Notes Mailbox master template, it should first need to be configure. But after configuring, I still cannot see the archived messages with stub icon. What is the reason for this? Can someone please provide the procedures on how to configure the Lotus Notes Mailbox master template correctly that can display the stub icon? Thanking everyone in advance.
