Setting up Exchange account on iPad

I use a gmail address and set up an Exchange on my iPhone, it works.

I set it up exactly the same on iPad and nothing shows up in Mail

I deleted the Exchange account and added it again, four times.

I rebooted the phone

I held iPhone up next to iPad to make sure I was doing it the same way

Does it work on iPad?

I'm up to date on both devices.

What am I missing?

Thanks!
