try this
start-run-regedit
browse to HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail\Microsoft Outlook
towards right double click DLLPath and paste the below
"%ProgramFiles%\Outlook Express\msoe.dll"
Please let me know if it worked.

Thank you, Vijay. Here's what happened when I tried that.

First, I made the change to the Registry. Then I made sure that Outlook
Express was set to be my default E-mail client. (I did this in the Internet
Options Control Panel applet -- under the Programs tab.)

Then I started up Outlook. Nothing else -- just started it up, and
immediately closed it. When I went back to the Internet Options window, the
default E-mail client had been *changed* to Microsoft Outlook once again!!
But when I went back into the Registry, to where I had made your suggested
change, it still showed the change -- i.e., it still pointed to msoe.dll,
not mapi32.dll. (However, there is another key at that same node of the
Registry, called DLLPathEx. It still pointed to the mapi32.dll file -- but
a different copy of the file. Instead of being in "%ProgramFiles" -- i.e.,
C:\Program Files -- it's pointing to C:\Program Files\Common
Files\SYSTEM\MSMAPI\1033\msmapi32.dll. I have not changed that entry, since
you didn't mention it.)

So something in Outlook is *still* resetting the default E-mail client. And
all I have to do is *open* Outlook -- nothing more.

I'm stumped... Any other suggestions?
