We have started receiving undeliverable messages to emails sent to another domain for our company (hosted through Go Daddy). I have tried deleting the addresses from the autocache and manually typing in but still receive the same undeliverable message. I have verified that the the email addresses are active and am able to send messages from Gmail without an issue. Any thoughts on why Exchange Online is kicking these back?
