To set-up a mail account in Outlook, Outlook express or Windows Live Mail, you first need to open up your chosen Mail program.
In outlook/OE you'll find accounts by going to Tools menu > Accounts/Account Settings > Add / New
Then you will need to configure the following options:
POP3 server (incoming) which should be included in your welcome e-mail
SMTP server (outgoing) which should be included in your welcome e-mail
You will need to create some mailboxes before you continue, you can do this from Mailbox configuration in your control panel.
Username: email@example.com and password you defined for the mailbox.
You'll need to also ensure you click advanced options > Outgoing mail and tick Use Authentication and Use same authentication credentials for outgoing server. If your ISP blocks port 25, please edit the port configuration to use port: 587
