Outlook 2000 using excessive CPU cycles

Strange occurrence when launching Outlook 2000. After about 10 – 20 seconds of the program running I noticed the CPU cycles (usage) shoot up to 60% and fluctuate between 55 and 60 until I shut down the program -Outlook.  With Outlook running this slows down the machine considerably.
Here are some other facts:
-no excess hard drive usage – just cpu
-removed all running programs and unnecessary system files from starting
-removed McAfee virus scan
-in Task manager you can see Outlook.exe and System Idle Processes going wild!
P4 2.8 with new hard drive – clean install of XP Home and Office 2000 Pro.
Has anyone seen this?

I have seen this before.  Make sure you have all of the latest service packs and updates for Office/Outlook 2000.  I believe this issue was somehow related to the calendar.  It was a problem with reminders trying to fire off.  Try going to start, run, type:  

outlook /cleanreminders

try exporting, then clearing your calendar.

Thanks Mark. Your idea of the latest service packs took me to Microsoft's site.  Although I had the latest SP3 pack I did find find Knowledge base article 811167 which addresses the problem directly.  I installed the 'fix' and all is well.
Thanks!
