Sorry I don't follow.
Your screenshots show an app which is not Aqua Mail and not InTune Company Portal app.
What app is that? Whose title bar says "Active Directory"?

Do you have InTune app installed and your account configured there?

1 - please choose "Office 365" as account type
Did you?
2 - there will be a blue panel near the top labeled "Log in with Company Portal"
Was it there? Did you tap that?
3 - tap this panel to actually log in
And then where do you end up?
In the Company Portal app?
Your screenshot has an app whose title bar says "Active Directory", that's not InTune Company Portal app....
