Download the Outlook app to your phone and click "Add email account"
From there, enter in your email and hit "add account"
Next, enter in all of your information just as I have below. The server name is the same as I have it, but replace the email and username fields with your own information.
At this point you will be logged in to your account, but will not see any emails in your inbox. We still need to allow this device to access email from the device manager.

Go to that text message and click the link. It will direct you to the device manager:
To log in, you will see the familiar authentication pages used for Intermedia services:
You can proceed to authenticate using the same credentials and 2FA method that you would use for any other Intermedia service.

To grant access to this application, click on the Activate button:
You will then be asked to confirm this action:
After which you will see that the Token Assignment Status has changed to Active:
