File Share Encryption

I have Server versions 3.2.1 (Build 4461). I try to revoke а key (client key mode) both as administrator and as user with next uploading revoked key.

But status of the key [valid] never change on the server ?!  Please, recommend me where a problem hides.

You can not revoke a CKM key from the Universal Server. This is Client Key Mode and all the key management is the responsibility of the end user. If you don't want the key to be valid anymore. Then open Desktop select keys, then select the key and right click it and go to key properties and select the expires option and make the key expire. It will no longer be valid upon that expiration date. Please mark this as the solution if this solves your problem.
