3.0 zentyal mail server cant connect to Outlook

[Csbonito]

Hello again!

Well I have Zentyal 2.2 has a mail server, I use Outlook to retrieve emails and I don't have any problems.

Now that a Installed Zentyal 3.0 Mail Server with the same configuration has my Zentyal 2.2, I cant connect with IMAP/POP to retrieve mails, but with SMTP the authentication works. I have tried different usernames on Outlook and nothing.

Am I missing something new on the Server?

I hope you can help me and Thank you

Are you using Dovecot or Zarafa? Can you post screenshots of your outlook configuration?
