Internet Explorer not saving options

I have several users with Windows 2000 SP2 (can’t/won’t install SP3) and Microsoft Office 2000 Professional. All users are using new Dell PCs.

When the user is in the Windows Explorer, and they right click on a file -> send to -> mail recipient,the email configuration wizard pops up to be set up for Outlook Express. They are using an exchange server, already set up through Outlook – this part works.

Looking at IE’s option tab, it shows to use Outlook Express for all pertinent lines.So I change the lines to be Microsoft Outlook. Hit Apply/OK, get out, and try again…

Have to create a new Outlook Express…

OK, what’s going on? Is there something that I’m obviously missing? Microsoft’s site is useless
