I am unable to add my Zoho mail accounts to Outlook 2010. The right settings are set up for them with my DNS Manager as I can send and receive emails as normal, but when I try to add the accounts to Outlook with POP3, I get an error when the program tests the settings. 

I have followed the instructions on this website. 

My email addresses are not @zoho.com, they are @mydomain. In this case is there a different process to follow?

Thanks in advance.
