Hi there to all Zimbra Guru's,

I have configured my zimbra server with public IP address, and the A record and DNS is configured well. I can send and receive emails from webmail without any problems or issue to all domains to and flow. But now when i want to configure the Outlook 2003/2007 to use Zimbra pop3 settings, im having some issue here. Everytime i setup the outlook for pop3 setting, when i click the Test message in the Outlook i got this error :

log on into incoming mail server (pop3) : outlook could not connect to the incomin pop3 mail server because the server did not accept your username or password

Could someone highlight me anything that im missing here or wrongly configured please ?

Thank you
