Hi @ElimGarak. Thanks for being part of GoDaddy Community! It's hard to say for sure what's happening in your situation without more information. My guess would be that your domain doesn't have the right DNS settings to work in conjunction with our email forwarding service. Please keep in mind that you can't use email forwarding while also using another email service (like Office 365). If you can provide more information on your situation, that may help others offer suggestions. Hope you're able to get this figured out.
