Anybody out there have on premise Redmine application running, and using Office 365 Exchange Online and Azure Active Directory? We configured Azure Active Directory to only allow modern authentication, but then Redmine e-mail notifications do not get through. I have found 'authentication error' message in one of the Redmine log files. When I make an exception in Azure Active Directory Modern Authentication requirement for the Redmine 'user', then the e-mails go through just fine.
The Redmine configuration.yml is currently set to SMTP delivery method to server smtp.office365.com, port 587. do I just need to change the server and port number to something else? I hope?
