- Best run some message traces, they should give you a clue as to what's happening: https://docs.microsoft.com/en-us/exchange/monitoring/trace-an-email-message/message-trace-modern-eac
Also, make sure that you have configured SPF for your domain as a minimum, and preferably DKIM/DMARC as well. https://docs.microsoft.com/en-us/microsoft-365/security/office-365-security/set-up-spf-in-office-365-to-help-prevent-spoofing?view=o365-worldwide
Have you confirmed the new domain name is in the list of accepted domains in Exchange Online
