Thanks, Claws (Paul) for your interesting ideas. We're a Lotus Notes shop and I will definitely follow-up with our Notes admin to see if he's aware of any inconsistencies on e-mail date formats stored behind the scenes. As I mentioned earlier, from a user perspective, the date formats all look the same on my Notes mail. That was one of the first things that I checked.

In the meantime, I will also take a look at the fix utility and try running it.

Appreciate the tip regarding view next unread.
