As Ido above mentioned, MS-Outlook is broken in so many ways, you’d be surprised that people are still using it. I can chalk it all up to the MS-Exchange lock-in, but the fact is that the number of Personal Information Managers available (integrated email/calendar/tasks clients) is pretty limited, and when it comes to Useful PIM clients (those that you fight with less then you get to do useful work) it comes down to MS-Outlook and… hm.. well – there’s Evolution if you don’t mind the occasional breakage. Most people mind though so that’s where we’re at.

BTW – Zedcar – I’m also using Evo with Exchange at work, and I haven’t seen the behavior your reported in Launchpad. Still I subscribed to that report, maybe I can comment more later.
