I wrote about the Outlook 2003 CPU usage problem a while back and so
far have not found a solution. But I think I have narrowed down the
problem.

I removed my PST file and created a new one. I downloaded all of my
email and then imported my contacts and tasks from the old PST.
Outlook runs fine now on Vista.

I then removed my sync settings for my cell phone and set that all up
fresh again. After I got it all resynced Outlook is now back to
constantly using 40%+ of CPU. It also will not shut down without
killing it. And I am not syncing any more. My phone is not connected
to the laptop. Yet Outlook uses the cpu.

So it must me the new Windows Mobile Device Center that is not
releasing Outlook. I do have Vista SP1 installed, too.

Any ideas how to fix this?

Does Outlook 2007 have this problem?

I answered my own question: Installed Office 2007 Small Business
Trial. Outlook still uses 40+% of the CPU constantly.
