To remove Outlook 98 completely from your computer, use the following steps.

WARNING: If you use Registry Editor incorrectly, you may cause serious problems
that may require you to reinstall your operating system. Microsoft cannot
guarantee that you can solve problems that result from using Registry Editor
incorrectly. Use Registry Editor at your own risk.

1. Start the Add/Remove Programs tool and remove Outlook 98.

2. Start Registry Editor (click Start, click Run, type "regedit" (without the
  quotation marks), and then click OK).

3. Locate the following registry keys, export each key to your desktop, and then
  delete each key from the registry:

  HKEY_CURRENT_USER,"SOFTWARE\Microsoft\Office\8.0\Outlook"
  HKEY_CURRENT_USER,"SOFTWARE\Microsoft\MSDetect\AllApps\EMAIL\Outlook"
  HKEY_CURRENT_USER,"SOFTWARE\Microsoft\Shared Tools\Outlook"
  HKEY_LOCAL_MACHINE,"SOFTWARE\Microsoft\Office\8.0\Outlook"
  HKEY_LOCAL_MACHINE,"SOFTWARE\Microsoft\Windows\CurrentVersion\App
  Paths\OUTLOOK.EXE"

4. Rename the following files that may still remain on your computer after you
  remove Outlook:

  Mapi32.dll
