Идентичный `ConversationId` для, казалось бы, не связанных сообщений

Question

У нас есть пользователь с десятью электронными письмами с одинаковым ConversationId. Также электронные письма имеют ту же тему. Однако сообщения электронной почты не принадлежат одному потоку (и клиент Outlook на рабочем столе пользователя не отображает их как поток). Смотрите пример:
