I dont disagree with you, but I was referring to Outlook 2003. My point is that it could be IE7 thats causing the problem with Outlook 2003 and 2007. (I'll dig into the indexing/rss things if I reinstall IE7)
I've had the same "slow" problem with Outlook 2003 on XP-pro when I installed IE7.
I however did find out that it is a "incompatible bug" in loading the security-settings in outlook 2003. (start OL2003 and open options|security|click-OK fixed the problem untill OL2003 was closed!!!).
Wierd things happen... How many have the "slow outlook" with Internet Explorer 7?
