Hi @Toolie,
Maybe setting the Apache LogLevel
to debug
in the httpd.conf
file helps you to get that information, but note it will make the Apache log file bigger very fast, so I recommend you to have it enabled the required time to do a quick test only.
You will need to restart Apache for changes to take effect
sudo /opt/bitnami/ctlscript.sh restart apache
Note the SMTP settings must be different when using Office365 instead of AWS SES, so we recommend you to ask in the official Joomla forums for further help on this.
