Hi,

For your question, we need more information about this issue. For example, internal or external mail flow, NDR or queue error.
We can check the setting for send connector as well as accept domain.

Here's some artile about troubleshooing mail flow, for your reference:

Hi Sikdar,

Ask user to login to OWA and ask to send email to himself. Also do you see new incoming emails there. If yes, you have issues with Outlook and client connectivity via OutlookAnywhere.

If no, there there is issue with the user account or your Exchange server itself.

Hi Sikdar,

Start reading about MS Exchange first, understand the product, get some training done on microsoftvirtualacademy.com
