What do you mean with online mode? I guess you mean Outlook in online mode? Yes, that is enabled. I don't see the pane at all. Only the pictures of the people that are in that specific e-mail.
We are using outlook 2010 64 bit on a Windows Terminal Server 2008. We have the outlook social connector installed and the LinkedIN connector 18.104.22.168 as well.
Most things work fine, like the LinkedIN address book and the pictures are visible. However the activity pane is not visible...
