Here are mail server settings you need to use if you’re trying to setup your email account with an IMAP connection with iPhone Outlook App.

You have to specify the port after the mail server with this mail application.

Below are what the mail servers and ports should be typed in as.

username: full email address
password: account’s password
Incoming IMAP mail server: mail.infoquest.com:143

username: full email address
password: account’s password

It will try to login and say it can’t connect with a secure connection, do you wan to continue, click the Login button again and it will connect.
