Add shared mailbox as emission email
I would like to add a shared mailbox (office 365) as my emission email address in Settings>Email Notifications.
I've added the email through the UI and have also edited the /opt/bitnami/apps/redmine/htdocs/config/configuration.yml file to add
But as it's a shared mailbox there is no password, I feel this may be what's causing the error;
An error occurred while sending mail (535 5.7.3 Authentication unsuccessful [DB6PR07CA0004.eurprd07.prod.outlook.com] )
Has anyone got any ideas? Is it possible to get rid of the authentication?
