I have Exchange 2016 with DAG configured in my environment. There are 2 DAG members and 1 Exchange Edge Transport Server.

Today I changed exchange certificate and assigned services to it, it gave me a warning to re-subscribe exchange edge in your site.

So I first remove previous subscription and apply new subscription on edge and mailbox servers. after re-subscribe exchange edge, there are now 2 entries being displayed under servers --> servers tab in ECP. one entry with proper edge transport server name and 2nd entry with CNF:95d1c2eb-********-ff9291471906. this entry is duplicate of edge transport server.

there are also duplicate entries under mail flow--> send connector. one entry is proper name, but second entry is duplicate with the same CNF which i mentioned above. For better understanding snapshots are attached.

edge duplicate entry: edge_duplicate_entry

send connector duplicate: send_connector_duplicate

Can anyone explain what is CNF entry? Can I delete it? Is this CNF duplicate entry harmful? please suggest.

Please refer to this blog about “CNF:” object, it seems a duplicate object, I think you could delete one of them. And here is a detailed article.
