The incoming mail server is dependent on the domain of your Unicom email address. The domain of your email address is whatever follows the “@” symbol. You should enter ‘mail.domain’ in as the incoming mail server, for example;
If your email address ends with “@unicombox.co.uk” then type 'mail.unicombox.co.uk' for your incoming mail server.
If your email address ends with “@unicombox.com” then type 'mail.unicombox.com' for your incoming mail server.
If your email address ends with “@unicomemail.co.uk” then type 'mail.unicomemail.co.uk' for your incoming mail server.
In the Incoming mail server (POP3) text-box, enter mail.unicombox.co.uk.
In the Outgoing mail server (SMTP) text-box, enter smtp.dslconnect.co.uk.
Click the More Settings button.
Click the Outgoing Server tab.
Select My outgoing server (SMTP) requires authentication, ensure Use same settings as my incoming mail server is selected, then click the OK button.
Click the Test Account Settings button and correct any errors that it identifies.
Note: Outlook's Test Account Settings procedure occasionally fails even if the account settings are correct. If it repeatedly fails and you are certain that the account settings are correct, skip to step 12, then test your setup by sending an email to yourself.
When the test gives you the message Congratulations! All tests completed successfully, click the Next button, then click the Finish button.
