Outlook Android unable to login to WorkMail

I cannot get the Outlook app for Andriod setup with WorkMail. I have the Outlook client on Windows setup but with the exact same configuration: email address is correct, server is outlook.mail.us-east-1.awsapps.com (I know I am on the us-east-1 server), Domain\Username is the full email address, Password is the correct password.

The Android Outlook app gives me the message:

Unable to Login
The service is currently unavailable. Please try again later. If the problem persists, please contact customer service (503)
