Jive for outlook does have capabilities of some theming options as well as updating settings.
Regarding the theming, this document provides more details for Outlook, but I wanted to provide a snip from the doc:
You can modify:
- The colors used to style the Social Bar and the borders of various dialog boxes.
- The Jive icon that's shown in the Social Bar, the Accounts tab, and the filter menu.
- The Jive logo image that's shown at the upper right of the social bar, as well as when you create a status update or direct message.
Additionally you can enabled and disable client features by creating an administrator script in the admin console and then pushing it to client machines. This document goes over how this can be done for Outlook. This is the reference document for which of those can be enabled/disabled for Outlook
Hope this helps.
