In order to help you solve this problem in a more timely manner, we would like to confirm the following information with you:

- Check the Default remote domain settings by accessing Exchange admin center remote domain in your organization, are there any recipient domains created for forwarding emails externally?
You can also perform a message trace for further investigation if you have Exchange admin permissions:
- Login to Classic Exchange Admin Centerwith Microsoft 365 global admin or Exchange admin credentials.
- In the EAC, go to Mail flow > Message trace. Click Start a trace and then input the sender or recipient email address and check the trace result. Then you can see the cause of not receiving emails internally or externally.
