    Hi

    In screenshot I can see you have smtp.office365XXX please change to smtp.gmail.com  and test.

    Below settings works for me.

    SMTP Server: smtp.gmail.com

    SMTP Server Port: 587

    Authentication: Basic

    User ID: Gmail address (e.g. mhgh@gmail.com)

    Password: Gmail password

    Secure Connection: Yes
