Hi goetz,

Outlook provide many features. One feature is that you can easily change the position of the Outlook folders. You can do that by directly drag and drop method (as you were using till now).

Apart from this, if you want to see them always on top then the best solution for you will be, moving the folder to the favourite folder. To do this, you need to drag the folder and drop them directly to the Favourite folder on the top of the Nav pane of your Outlook window.

Thanks & Regards,
