I am trying to help a neighbor with an email problem.
She cannot open any email links that are presented in either an email or a web page.
She can open any web links, just not links to an email address.
She has Windows XP SP2 with full updates.

This is what I have done so far:

I ran the re-register command
"C:\PROGRAM FILES\OUTLOOK EXPRESS\MSIMN.EXE" /reg
I checked the file types
URL Hyper Text Transfer File Protocol
URL Hyper Text Transfer File Protocol with Privacy
and found
"C:\PROGRAM FILES\INTERNET EXPLORER\iexplore.exe" -nohome
I checked the path to iexplore.exe to make sure that is correct and uses the
double quotes.
DDE was checked and in the boxes below it read:
#1:
"%1",,-1,0,,,,
#2
IExplore
#3 (blank)
#4
WWW_OpenURL

I also checked the URL mail to Protocol
and found
C:\Program Files\Outlook Express\msimn.exe as the program
DDE was checked
application was "msimn"
type was "system"

I went to the registry
HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail\Outlook Express
and found
C:\PROGRAM FILES\OUTLOOK EXPRESS\MSOE.DLL for the dll path (and msoe.dll is there)
just as suggested in MS KB Q306098

Anyone have any more suggestions or ideas?

Add that her email program seems to be working just fine.
Only that when she attempts to use a email address link, she get the message.
Your default email client is not properly installed (or something like that).
