This is a very useful app, picking up all of the LinkedIn contact details from the email addresses in any email you have received. It show the profile, gives you the ability to connect, see their recent activity, their company.
BUT, initially in the Outlook client I could only see the LinkedIn contacts as if not logged in to LinkedIn, with no connect button. Following reading one of the other reviews (thanks!) that said you had to go and log in at the Outlook Web client, I simply went there, was logged in already, but when I came back to the Desktop client all was working properly for the first time and you can do a 1 click connect on LinkedIn for someone new.
So now I can say Recommended.
