How to get to the SMTP (Outbound) email server settings on iOS 10.0.2

How to get to the outbound email sending server settings (SMTP) on iPads or iPhones running the new iOS 10.0.2 operating system. (Where the Email, Contacts and Calendars button has been replaced with three separate options).

This video might be helpful for those who have to "blindly" / remotely support iPad or iPhone users and don't have an iPad or iPhone to test with themselves.

Sorry for the heavy redaction on the video. The iPad I was filming wasn't mine.
