I think it would be good if Jive for Outlook could highlight the new messages. As it is, if there are five messages displayed on screen when I click on an email, it's not obvious where I should start reading. That's made doubly difficult by the fact that I might have clicked on the email timestamped 17:15, but on the Reading Pane I see the messages timestamped 17:15 AND 17:16 (albeit without the time actually being displayed!). That's a little counter-intuitive, since coming from traditional email, I don't feel like I've got to the 17:16 message yet (it is still shown in bold in my email inbox to show it is unread).
Michael, you should create this as an idea instead of a discussion so that people can vote on it.
