I have set up the email according to the google recommended settings but the test e mail fails to send, any help ?
You might have to enable login for less secure apps in your Google account.
And make sure you’re using port 587, rather than 465.
If you are using Desktop Edition on a Mac, this is a known issue. For the time being you won’t be able to email from within Manager.
What versions of your OS and Manager are you using? and the specific error message?
