What can I remove from Exchage 2016 server keeping only smtp relay service and object management?

Hi, I'm wondering what can I do to minimize the 2 Exch 2016 server hybrid environment now that there are no mailboxes but I still want to keep them for smtp relay and user attribute management.   ...

    I would remove the DAG (how many servers are you retaining on-prem?). In theory you can remove the last mailbox DB, but you'll have to remove all the system mailboxes prior to that, which can be problematic, so I'd generally recommend keeping one mailbox DB. You can remove the hybrid configuration as well (some steps are in this blog from Microsoft). Just retain the connectors that route messages to/from EXO (they won't be automatically removed if you remove the hybrid). The hybrid license won't be removed, and you should be fine with any audit as long as you aren't hosting mailboxes on the server with the hybrid license.
