The Archive Chat feature allows you to hide a conversation from your Chats screen and access it later, if needed. You can archive group or individual chats to better organize your conversations.
Note: Using Archive Chat does not delete the chat, nor does it back up the chat.
The chat is now archived and will not appear on your Chats screen.
Archived chats will also reappear when you receive a new message from that contact.
Learn how to use Archive Chat on: Android | iPhone | Windows Phone | Nokia S40 | BlackBerry | Nokia S60
