Built-In Email App *Buttons Grey*

When loading the built-in Email app I am presented with an form that says "You can configure Email for most accounts in just a few steps" with two text boxes (Email address and Password) and two buttons on the bottom (Manual setup and Next).

I can enter both Email address and Password but both buttons "Manual setup" and "Next" are greyed out and I cannot proceed any further... Any ideas on what I can do to revive this app?
