Saving files to folders in Dropbox and not the default “One Note” such as right click “Save”and Printing direct from the email and not having to save it first.

How do you save a file to Dropbox where all my folders are saved? I do NOT want to save to One Note which is a great app for people working. I am retired with a home desktop and I like saving to my very organized files in Dropbox.  Also, I am not able to print an email when it's open. What I get is the right pane, the ads and a partial copy of the email itself. I used to be able to right click and print. Or right click and "Save As." Why would you change that? I DO NOT LIKE ONE NOTE. Please help me.
