I'm locked in to Outlook 2007 at work, and I've had a pet peeve for years now.
15-minute reminders are de rigeur wherever Outlook is used, so let's say I have a 4:00pm meeting.
At 3:45, I get a pop-up saying "meeting is starting in 15 minutes". The default interaction here is "remind me 5 minutes before the start".
At 3:55, I get a pop-up saying "meeting is starting in 5 minutes". The default here is "remind me in 5 minutes".
What I'd really like is for it to remind me in four minutes, because in five minutes I'll be late, but if I leave now, I'll be four minutes early. As configurable and pluggable as Outlook 2007 seems to be, I am unfamiliar with any changes that affect snooze and make it actually useful for the 99% case of "user has to go to a meeting, and would like a reminder at the right time to stand up and leave." Are you?
