Contact History
You can view and manage previous interactions with a contact by selecting them from the Contact Directory or the Information view of the current voice, chat, email, or work item conversation. Contact history is a way to maintain track of all of your communications with a customer, which will be quite useful in solidifying your relationship with them. So, whether you've gotten an email, made or received a phone call, or even received a letter, this is where you should record it because it gives you a complete history of communications and makes it visible to all users.
