Conversation Clean Up | Issues

Hi,

I usually copy and paste the body text of a message and send it to different recipients.

Although the text is similar, they are completely different conversations but Conversation Clean Up F&S deletes all the messages except for the last one.

I don't see any settings in File/Mail/Conversation Clean Up that can be of help.

How can I prevent the Clean Up option of deleting equal body messages but with different recipients?

Thanks/Brgds
