I’ve seen several complaints about the following problem recently, so I think it’s time to address it with a tip.
In Outlook 2007, the Today flag is the same color as the No Date flag. This makes it hard if you use the flag colors to help triage your mail. So, rather than using No Date flags, use the Next week flag. While it’s easy enough to change the default flag for new items (right click on the flag field, choose Set Quick click, pick a new default), how do you find and change the existing No Date flags?
When finished, remove the Due Date field and turn the reading pane back on.
