I'm helping a friend with GSuite. They were running it for optimodesign.com but they let that domain expire and someone else grabbed, so, we added optimodesign.com.ar as an alias.
I've configured the DNS and GSuite to work with optimodesign.com.ar and everything looks ok in the admin tool. It looks exactly the same as my other GSuite accounts where the alias is working:
When I send an email to an @optimodesign.com.ar email address, I get an "Address not found" response.
Any ideas why?
