I'm not sure, but I think the Subscription plugin will only work on Spark IM Client.
You might want to try Client Control plugin for client restriction, but will work only on Spark.
Also, the Packet Filter plugin works great to restrict users from chatting to other users not on the Group/Team/Department.

Subscription is only about presence (status). It shouldn't block messages.
