Common identifiers for mails in conversation - Aspose.Email - Java

We are using Aspose.Email for Java Version 17.2 to parse MapiMessages from a PersonalStorage class.

We would like a single identifier to reference multiple mails in a conversation, the way outlook does. Towards this, we have tried to read PidTagConversationId = 0x30130102 and MapiMessage.getConversationTopic() .Unfortunately, neither of these fields addresses this need.

Can someone please point out how we could use the Aspose library to achieve our requirement?

Regards,

Shankar
