HVE (High Volume Email) connection in D365 CE/CRM (online)

Hi all,

Has anyone successfully been able to create one of the new HVE “mailboxes” (doesn’t actually show up as a mailbox per se, but for lack of a better term) and connect it to their D365 CE/CRM (online) tenant?

I created the HVE itself in ExO:

But I can’t find clear documentation on how to connect that HVE to D365. Can anyone shed light on this?

Thanks!
