Outlook plugin on EV 10.0.4 R1 server?

Hi,

In previous versions I have never installed the outlook add-in on ev servers since it's not required.  However I would always see the ev outlook plugin buttons if I launched outlook on the ev server.  This is useful sometimes for troubleshooting, especially for journaling (cancel operation on stuck items, etc.).

I recently installed EV for Exchange 10.0.4 R1 for journaling only.  I don't see the EV buttons when I launch outlook on the ev server. 

Do I need to install the plugin or is there a reg-key or policy setting I need to enable to see the EV client on the server?  I am logged in with the ev service acount.

Thanks,
