Important note: These registry changes are provided as examples of how these parameters might be changed. Be sure you have a complete backup of your registry and an up-to-date ERD (Emergency Repair Disk) before you make any changes. The Registry editor can make your system unusable, so be careful! We take no responsibility for these registry changes - do them at your own risk!
I don't know about you, but when I get email attachments I like to be able to find them.
For Outlook XP:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\10.0\Outlook\Security
For Outlook 2000:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\9.0\Outlook\Security

Double-click "OutlookSecureTempFolder" and modify it to the desired location.
