There are a number of productivity features that Jive for Outlook offers. I would recommend reading more here:
As mentioned in the documentation, the plugin requires a license. You may check your existing license to see if it includes Jive for Office by navigating in the Jive Admin Console to System > Management > License Information and look Outlook Module. If this is missing, you'll want to contact your Jive Account Manager to inquire about adding it.
Let me know if you have any other questions with this.
