Definitely do not disable SMTP authentication and be an open relay for anyone to SPAM through your mail server. It's possible that Gmail supports other security features (possibly one of ENHANCEDSTATUSCODES, CHUNKING, SMTPUTF8) that we don't, allowing an alternative to SMTP authentication that outlook is happy to continue with. However, Only Allow Secure Login forces users to use a secure login method ideally via STARTTLS with SMTP authentication so that everything is encrypted and secure.
