Would you like to be able to see the time you replied to or forwarded a message in your message list view?

You can, using an Extension form configuration file (*.CFG) that exposes the hidden Extended MAPI property PR_LAST_VERB_EXECUTED, which holds the replied to/forwarded times. The best part is, you don't need to have a clue about what I just said. :)

Michal Bednarz of CodeTwo (and a Microsoft Outlook MVP) wrote a 'Last Action' CFG file. It exposes the fields for both the time and action (replied/forwarded). You can download it from http://www.codetwo.com/downloads/CODETWO.LASTVERB.CFG
