I'd like Outlook to mark any messages I delete to be marked as read. For bonus points, I'd like it to only do this on messages that I have opened/previewed before pressing delete since this means I've looked at the content and chosen to delete it.

I know I can set it to mark as read after x seconds when I'm looking at it, that's not what I want. I also know that I can move off the message & back on to it or right click to mark as read - still not what I want.

I'm using Outlook 2007 in case that matters.

[Edit: I just found I can at least mark as read with a keyboard shortcut: Ctrl-Q, but again, it'd be nice to not have to do this. More shortcuts here.]
