Fixing Office365 Mail in OpenForis Arena with STARTTLS
The OpenForis Arena platform comes with built-in email support, but the default configuration does not correctly support STARTTLS when using Office365 SMTP servers. This causes the entire mailing service to fail — which means new users cannot register, and existing admins are unable to invite users to join the system.
This guide explains how to patch the email integration to work with Office365 using NodeMailer, configure the necessary environment variables, and deploy Arena using Docker Compose — complete with working email functionality and GitHub package authentication for building the image.
