In Thunderbird I set my &quot;saved&quot; folder to be my Inbox, so that all related messages are together, and when I&#x27;m visually searching for something I see it no matter who sent it.<p>In Outlook I do similar, but I have incoming messages redirected to my Sent folder, because you can&#x27;t (I think) change where sent messages are saved. &quot;It&#x27;s Sent, why would you want sent messages to go anywhere else?&quot;
