ConversationId property vs ConversationIndex property in Exchange Web Services managed API RRS feed

  • Question

  • EWS Managed API have two properties:ConversaionId and ConversationIndex

    What is the difference between them? I guess ConversationId is the the ConversationIndex of the first mail in the conversation which is essentially of 22 bytes, while ConversationIndex is the index of that particular reply in the conversation thread, essentially of 22 bytes + multiples of 5 bytes for each reply in the conversation. Is it like that?

    Also ConversationId is accessible only with Exchange Server 2010 onwards. So cant we access ConversationId in the Exchange Server 2007?
