I'm not sure exactly what you asking, it sounds more like a mail server question.

Somethings changes:

Now i have an Outlook 2013 with email@domain.com configured with inbox there with 200 msgs
 and i have this same domain.com configured into Plesk with Roundcube.

i would like to import this 200 msgs (from my outlook inbox) to the email account on Roundcube Inbox.

I'm guessing that the Outlook account isn't using IMAP so unfortunately I can't really be of much help since I don't know much about Outlook.
