Since you didn't mention what operating system is involved in the equation,
the first and formost things to check a

1) Security software like antivirus that does real-time scanning of files.
I would exclude the program from being able to scan the .PST file type.

2) Does she have any third party applications that integrate with Outlook.
(These would be addins that *might* be listed under Tools Options Other
tab Advanced Options Addin Manager and/or COM Addins.

I am wondering why my wife's HP Laptop with an AMD Touron chipset runs slow
when she tries to delete emails from outlook. I observed the computer's
performance with the task manager resource meter and have noticed that
when
she deletes email, the CPU usage spikes to 100% which appears to be
causing
the computer to become unresponsive. Given enough time the computer
sometimes returns to normal when the email is finally deleted or stays
unresponsive. I don't have this problem with my older HP laptop. What is
likely causing Outlook 2003 to do this?
