Thunderbird email › Question about Outlook Express

Outlook 2011: How can I get rid of the day/date bars in the item list pane???

I work at a place with an Exchange Server and have been using Mozilla Thunderbird, which kept me from using all the Exchange features.

I just did major updates to my iMac, including Office 2012.

I used to think that Outlook was one of the most brain-dead apps in the world, but now I'm giving it a try to see if its useable.

I've actually managed to import all my Thunderbird email into Outlook and I'm customizing the interface so its comfortable to me.

But the one thing that keeps annoying me are the silly day/date bars in the item list.

You know, the ones that say Today, Yesterday, The Day Before Yesterday, and so on.

Is there any way at all to make them disappear?????

And, yes I know they're collapsable, but that just wastes more screen real estate with bars that have no content.

I want them gone.
