Error Settting Outlook 2013

Hi, I’m setting up my mail in Outlook, Virtualmin I installed on my server and send me the following error http://www.screencast.com/t/FX5B9oa3r1. I should do to run my mail in outlook?

Log onto incoming mail server (POP3): Your e-mail server rejected your login. Verify your user name and password for this account in Account Settings. The server responded: -ERR authentication failed

username and password are correct

in turn I get this error when sending mail, only I happen with those, I tried, Gmail. Hotmail and corporate without any problem, I think it has something to do with Outlook
