Here is a repost of a reply to someone with a problem with Outlook and Hughes mail by one of the Hughes Mods:
Firstly, I want to make sure that you have re-registered with Support Center via »my.hughesnet.com
using the same, exact email address that you used previously the first time you registered. Also, please make sure that your password contains at least one upper case letter. If not, please re-register with the same email address used previously to log in, and change your password to contain at least one upper case letter.
Next, please confirm that your Outlook is set to access the same, exact email address that you were using previously before registering with Support Center and that you can also access this email via webmail in Support Center at »my.hughesnet.com
. If you can not access webmail, please change your password and make sure that it contains at least one upper case letter and log in again.
If you are able to log into webmail successfully, please ensure that you are using the same email address and password in your Outlook settings. Also, please confirm that your Outlook settings have the following:
Incoming Server - mail.hughes.net
Outgoing Server - smtp.hughes.net

Hope this helps.
