Navigation bar Outlook

Hi 

I have the new version of Outlook, and the navigation bar is now on the left side but i would like to change it to the bottom. But here is the problem in the new version there is no ,,File" like in the previous one where it could be easily change and there is no ,,Advanced Settings" also.  I've tried the thing with the ,,windows +R" but it also doesn't work for me. Do you have some advice ?
