How to clean up clutter in Outlook 2013
When Microsoft released Outlook 2013 last year, they focused on modernizing the look and feel of the interface but didn’t do much to remove some of the clutter.
One tip you may find useful is to minimize the Outlook Ribbon. Pressing the keys CTRL-F1 in Outlook will hide the Ribbon from view, I’ve found this especially useful when you’ve double clicked on an e-mail and want to view it in full-screen. You can easily toggle the Ribbon back on by repeating the step above.
