How to downgrade from Outlook 2003 Std to Outlook 2000 Pro and XPs.
Assuming you're using a POP account, first create an Outlook97-2002-compatible
PST and copy all your folders to it. Outlook 2000 cannot read the PST files
Outlook 2003 creates by default. Save that PST to a known location.
Uninstall Outlook 2003. Install Outlook 2000, in either Internet Mail Only
mode or Corporate/Workgroup mode If you aren'tusing IMAP, I'd choose C/W.
Use the Mail applet in Control Panel to create a new mail profile and add the
PST you created to the profile, making it your delivery location. Start
Outlook and it should appear as close to what Outlook 2003 appeared as
possible.
