Hi @JustinMicheal-7973

Please share some more detailed information so that we can better understand your question.
For example, do you have a hybrid deployment?

And please post the NDR message which contains the reason why the messages were rejected as Andy suggested.

Hi @JustinMicheal-7973

Since you have a hybrid deployment, here is a Microsoft KB on this issue for your reference:
Users in a hybrid deployment can't access a shared mailbox that was created in Exchange Online

Please follow the solution in the link to create an on-premises object for the cloud mailbox.
And see if it can resolve this issue.
