Hi @hybrid fe ,
Welcome to our forum.
In order to resolve the issue more efficiently, would you please help collect the information below?
For various reasons, there are times when Active Directory may encounter a situation where multiple objects appear. The duplicates will be named with a CNF: [GUID] on the end of the name.
You could try to delete the object with CNF.
Besides, if you mean duplicate Edge Transport Server. You can refer to this article: 2206666-duplicate-edge-transport-servers-display-in-ecp

Hello
i'm watting a reply
Hi,
Thanks for your reply.
I am currently doing some research on this issue and will inform you as soon as possible.
Please be patient for a while.
Hi,
Sorry for the late reply.
Transport rules that you create are stored in AD, when you create, modify, or remove a transport rule, the change is replicated between the domain controllers in your organization.
And CNF means conflict. This can happen when AD replication is slow, and you can try to remove duplicate AD objects.
For Example: The first object creation will likely have already replicated before the second object is created. When the replication interval is reached, the DCs replicate and a collision occurs. The object that was created last will "win" and be kept, whereas the object that was created first will be renamed with an RDN in the format <original name> CNF: <objectGuid>. You will need to manually delete one of the objects, ideally the one marked "CNF." You can also delete the non-CNF object and rename the CNF object.
For more information about AD duplicate object names, you can refer to this blog. 15435.active-directory-duplicate-object-name-resolution.aspx
Thanks for your understanding and support.
