You are using office365 and you getting the error message because somewhere in your website something is overriding the email you
defined to send emails inside the plugin.

For example:
You configured in the plugin to use the address this address always needs to be in the “From” field of the outgoing emails, and somewhere else you have a different address defined.

You can do one of this possible solutions:
1. find the address and change it to the one you used in the plugin.
2. Block changes from external places inside the plugin ( “Show All Settings” under the wizard button):

3. Use this code inside your theme functions.php file:

add_filter('wp_mail_from', 'change_contact_from_address', 999);
function change_contact_from_address() {
     return '';
