When we duplicate an object, let's say a product with the name "Product", it gets the name "Product (copy)".
The first message of this product gets the subject "Product (copy)", too.
Now when we change the name of the product to "Vegatable", the subject of all messages still is "Product (copy)".
The Problem is, that when we send messages to the object (product) "Vegetable", the subject of the messages in the inbox is "Product (copy)". And that's really confusing for us.
How can we solve this?
