Trying to configure IMAP integration in CRM results in CONNECT ERROR

Trying to configure IMAP integration in CRM results in CONNECT ERROR

I am sure my account works fine (in Outlook POP3 and in Andoid IMAP) but I am unable to make it work in the integration. I have tried all the options. When I update the configuration, it begins to turn around until I receive the message.

Antyy suggestion? Thanks in advance.
