I was skeptical when I first saw this post at gHacks. Microsoft has a hotfix which is going to be bundled with Office 2007 SP2 which should come out soon.
Anyhow, the patch or hotfix speeds up Outlook significantly. The load time from clicking on the icon as well as the closing time. Also switching between folders is a lot quicker. This is a godsend.
Now only if they would fix the IntelliPoint bug where if you have accelerated scrolling switched on to fast, that it would act the same within Outlook – it doesn’t even work (accelerated scrolling).
