My client is a publicly traded company who uses Outlook for email. I created their app but now no one can login because the login code email does not arrive in their inbox. It works for outside email addresses (email addresses not affiliated with the client), but messages from no-reply@user.appnotify.io to my client’s email domain do not arrive.
Is it possible that their server blocks these messages? Has anyone experienced this before? Does anyone know a work-around?
Thanks!
