When I'm mail corresponding with a person and we both use reply (the topic remains the same) to answer I'm always getting the new correspondence in a different email/file. When we are talking about dozens of replays a mass of redundant mail is created. How do I Force MS outlook's 2010 email correspondences into to one file ?
A good example for the desired situation is in Gmail where email conversations are grouped together by default.
Secondly if the person I'm corresponding with changes the subject or don't use reply to answer me how can I merge this correspondences with other email(s) which for me discuss on the same topic ? (I tried drag & drop but it didn't work)
