Outlook Social Connector, cant switch to it.

Hi

In my People's pane I don't have the option of switching to the social connector.
Anyone know why?

I have installed and connected to LinkedIn.

Connected to Exchange 2010
Using Outlook Professionel Plus 2012 64-bit.
It's the same on several computers, Windows 7 64-bit, Server 2008 R2. All fully updated, Office should be too.
