In Outlook, when viewing an email that you have either replied to or forwarded in the past, it will say either "You replied to this message on DATE/TIME" (along with the icon showing a purple arrow pointing to the left) or "You forwarded this message on DATE/TIME" (along with the icon showing a blue arrow pointing to the right). How do you remove that replied/forwarded indicator?
I came across a method in the past that worked. It involved exporting the message, deleting it, and then reimporting it into your Inbox. But I just tried that and I still see the indicator, so I must be missing a step. I'm using Outlook 2010.
