I am using Exchange Server Webservices Managed API to move all mails belonging to same conversation thread to a specific folder. Folder for first mail in the conversation is specified by the user which is when I store its conversation index and folder name in database. Subsequent mails in the conversation should be moved to the same folder by the code automatically.
My problem is if it is possible that conversation index of two mails can be same if the conversation is originated from two different servers possibly of two different type. For example if the user have Exchange Account and sends a mail creating a conversation
thread 1. Also a user receives a mail from Lotus Server creating a conversation
thread 2. Is it possible that conversation
thread 1 and conversation
thread 2 can have same conversation index?
