Fortunately Outlook 2013 has an option that allows you to move the Quick Access Toolbar below the ribbon. That location can lead to misclicks, which can be frustrating if it happens to you with some regularity. However, you may also find that you accidentally click some of those buttons when you don’t mean to.
This toolbar provides one-click access to many of the features that you might use frequently in Outlook 2013. The Quick Access toolbar is a row of small icons that is displayed at the top-left corner of the window in Outlook 2013.
