We were trying to connect WP Mail SMTP to G Suite, but it wasn’t working. We kept getting a 403 org_internal error (“This client is restricted to users within its organization”).
We had followed your official guide, but had forgotten to do one of the steps (I forget which, unfortunately). After fixing that though, the plugin was still giving that error. I tried it several times but it kept throwing the same error.
Finally, I tried it in a fresh session (Incognito), and it worked on the first try. So it seems like there might have been some kind of cache or cookie related issue going on.
The rough steps for reproduction are:
1. Set up a G Suite app for your website, but skip an important step or two
2. Try to connect WP Mail SMTP to G Suite
3. Receive a 403 error
4. Fix the missing details
5. Try to connect it again
6. Still receive a 403 error
If nothing else, it might be worth adding that possibility to your guide. I don’t see anything about the 403 error in your troubleshooting steps, which makes it hard to know what to do to fix it.
