Outlook 2007 hanging when first opening ?

[dandownunder]

Hi Guys, am fairly new to Vista, have been using it for a few weeks now and my only complaint is that when I go to load my Outlook 2007, it opens pretty quickly but then just sits there loading away for about 45 seconds to one minute, then all my message display. Anyone know why this is ?

Running it on Vista Business With Mcafee on a T7200@ 2.00ghz, 2GB RAM etc.

Any help would be greatly appreciated.

Regards

Dan.

How big is your .pst file? I've seen it take a long time when you first load outlook 2007 if the .pst file is > 1GB or so.
