try without your antivirus and it's self signed certificate.
hello, issue still not fixed after disabling the antivirus and it's self signed certificate. Please suggest next steps.
see my reply under question "IMAP Office365/Outlook OAuth2 Authentication Failure"
had to change "authentication method" to "Normal password"
