A system and method allows an email user to solicit an email thread from another user (or from a server) in situations where the first requesting user may have been added to an email thread after the email thread was started, or in situations where the user may have an incomplete thread (for example, where a user is being added to a thread where an attachment was removed). The complete thread is returned to the first requesting user, after permission has been sought and granted, and after data mining and intelligent aggregation of a plurality of relevant threads in to one interleaved result is performed and returned to the first requesting user.
