I was trying to configure the Google apps in open-project. can any one guide me step by step configuration for editing configuration.yml and to add google apps (newbie here)

Hi Robin,

the configuration.yml.example file has an exemplary setting for all usual methods of outgoing mail configuration. You’ll only have to look up the connection details for Google apps and fill in.

The examples are shown here: https://github.com/opf/openproject/blob/dev/config/configuration.yml.example#L41-L92

Best,
Oliver
