Migration went well, exchange is up and running and functioning for but I cannot get e-mails to be received on

We are using Trend Micro Hosted E-mail and getting an NDR sent back: #554 5.7.1 <>: Recipient address rejected: Access denied ##

I have added as an accepted domain.
I have adjusted email policy to add this an smtp address, and confirmed it was added to the mailbox user
I have added the IP address range for Trend on the receive connector to allow e-mail to be received.
