Technologies are described for chronological re-ordering of transmitted conversation components. A message transmitting a message chain in the conversation through a forward or reply action, or addition of a new participant may be kept at the top and the remainder of messages may be re-ordered in chronological order. In some examples, the displayed properties (metadata) or header information may be normalized, that is displayed in a consistent manner. In other examples, flat header information (textual data) may be analyzed and enriched. Thus, the header information may be presented with interactive features such as presence information, calendar presentation, and comparable ones.
