Hi @Annette - Cascoat,

Thank you for your prompt reply, as well as providing more details on this issue you mentioned.

Since you mentioned that you're able to send out emails using your personal email address but not your business email, I suggest you contact the service provider for your business email to see if there's any setting that needs to be enabled.

Drop me a comment below in case you have any other questions in mind. I'll make sure to get back to you.
