Why can’t I add my outlook email to my iphone?

I have tried that but it didn’t help. It’s like the phone won’t accept any accounts from outlook at all.

I’m not even getting access to a log in screen when attempting to add an account specifically from outlook.

I’ve added pictures of what happens:

First I try to add my email by pressing on the outlook button.

Then this little pop-up comes up for a split second, where I’m supposed to log in to whatever account I have.

And then it goes straight to this. No log in or registration of any kind.

If I finish THAT process I get a new account in my accounts list simply labeled '?'.

If I go into that one it looks like this:

It tells me the account isn’t verified and that I need to re-enter password.

I can’t even change the mail address or do anything since it’s greyed out. If I try to re-enter a password I just get the same pop-up window as earlier and I’m back to the page above.

The problem Isn’t the password, it’s that I can’t add or do anything with outlook when trying to add it to my account.

Also I have no problem accessing outlook on any other device or service other than my iphone if that helps.
