'Usage
Dim instance As ConversationHeader

In Outlook, a conversation groups messages that share the same subject and belong to the same thread. A conversation can also include branches, such as when a message gets two or more responses and discussions grow independently from each response. The Conversation view relates all items in the same conversation across folders and stores. A conversation header can be an item or a group header in one of the following forms:

  • An item in a thread that contains only a single item.

  • A group header for a conversation that contains multiple items.

  • The first item in a conversation that contains a single thread.

  • The first item in a split conversation.
