IMAP - Unable to Login to Outlook App on iPhone

IMAP - Unable to Login to Outlook App on iPhone

Whenever I try to login to my email addresses in the Outlook App for iPhone, I'm getting an error saying that it won't login because of the username and password.

It only will let me login if I use my admin credentials, but if I use one of my 9 other email addresses, I get an error.

Please help.
