Email Folders

Hi: is there a way to make, add or even rename folders in your email?

I would also love to know it.

At least in regard to Exchange mail, it comes from the server.
So what ever I got on my Work Desktop, is being reflected on my iPAD.
And yes it looks terrible. I have lots of directories and sub directories, and on the iPAD it shows up as a long consecutive list . No way to change it.
