thanks for the reply. at least it confirms my suspicion that email routing can’t be reset to a fresh state.
the reason i want to reset this to a fresh state is an issue i’m having with cloudflare zero trust, not receiving codes via email. i suspect the inability to reset email routing to a fresh state may be responsible for it.
as in, internally zero trust considers the disabled state of a domain’s email routing as broken configuration and doesn’t send emails to that domain that is now has its mx records pointed elsewhere.
Email routing is fully disabled so this would not have any impact.
It’s most likely an issue with access policy:
If the email is allowed by an Access policy, you will receive a PIN in your inbox. Note: By design, blocked users will not receive an email. The login page will always say A code has been emailed to you, regardless of whether or not an email was sent.
