You should provide more information. Do you mean you think your program should already get the last email reply time but it doesn't seem to, or that you have everything else but you don't know what that field is called in Outlook, or that you're getting an error message, or what?
If the second one, I don't know what it's called either. In fact, I'm not sure even what you mean by "last email reply time"; is there more than one reply date in Outlook? What I think you should do is take the Item object in your program and put it in your Watch window; then expand its fields and browse through them looking for the ones that look like dates. Presumably if Outlook has the datum you want, you'll see it there and get get its name from the display.
