The WHD Guide mentions setting up an incoming email account with OAuth but no way to configure the outgoing account. I wanted to see if anyone has set up the outgoing gmail account using OAuth.

As Google, like Microsoft, are not forcing anyone to use OAuth for Outbound Mail I have never thought it is worth the effort getting this to work. As you may have many endpoint devices which use SMTP then I cannot see that going away.
