Hi, I recently had to do a eDiscovery search end export emails that should have contained only emails exchanged between two persons, with no one else in the exchange.

So case when user1 is sender and user2 is only recipient and case when user2 is sender and user1 is only recipient. In each case I wanted to have only them in search results. But it seems to be impossible to perform this query, and I was returned results with others in TO/CC/BCC.

Only way to do this (had MS Premier support work with me on this) is to export search reports in CSV, add "Yes" in a specific column for emails we need and then feed that list back to search.

This is very cumbersome and error prone.
