Is Outlook the only Office program installed? Have you tried renaming all
mapi.xxx files to .old and run fixmapi.exe?

After furious head scratching, Corn asked:

| Windows XP Pro, IBM Laptop
| Uninstalled Novell Groupwise email program
| Installed MS Outlook 2003, program appears to work as advertised when
| I start it and I am successfully using email, calendar, tasks, etc.
| However, anytime the email is invoked from clicking on someone's
| address link or from a visit to a website, IE goes nuts. It opens
| 50-60 different windows of IE, apparently until it runs out of
| memory. I then get an error message in a box that says the default
| mail client is not properly installed. Only way out is hard boot.
| Outlook is definitely set as default mail system in IE Tools. I have
| also tried to run outlook.exe /checkclient with no result (found this
| in technet)
| How can I fix this problem?
