If a card is added to Trello, send an email. Use to notify an Office 365 Group of new tasks.
Add a task to a Trello board... send an email. I wrote this so that, when a task is added in Trello, an Office 365 Group can be notified of the new task. The new task creates a new "conversation" for the group, and includes a link back to the card. The only trick is to use the Group's email address (from the group, choose View Details to find its address) as the RECIPIENT of the email.
