IN MS OUTLOOK 2013, if you reply to a message, then you go back again and open that email, you should see a line that says "you replied to this message on ...". I want to disable that message anymore. where we can configure it?
There's no setting for that. You could delete the information from every message. See the VBA help for how to use the PropertyAccessor. It's the PR_LAST_VERB_EXECUTED property that you'd need to delete.
