Exchange 2007: Outlook Web Access, a date oddity

I'm on the new version of Outlook Web Access (OWA) now, which I've been looking forward to ever since I read about some of the new features in Beta 1 on You Had Me At Ehlo (in my opinion, one of the best blog names ever). There were no burps or stumbles in the move over, at least not on my end. But there are a few things I'll have to get used to. One of them is the grouping of emails in the Inbox -- can't seem to get rid of it like I can in Outlook. But what I think is a true oddity is the date in the email list. Take a look at a sample from my Inbox:

I've sort of figured out the rules.

  • If the email was received on the current date, display time only.
  • If the email was received before the current date but within (unsure here, possibly the past week?), display day of the week and time.
  • If the email was received before (still guessing the past week) but during the current month, display day of the week and short date.
  • If the email was received before the current month, display long date.

What I haven't figured out, not even sort of, is the thinking behind all of that!
