257824 OL2000: Differences Between Outlook and Outlook Express



SYMPTOMS
Uninstalling Microsoft Internet Explorer 5.01 or Outlook Express 5.01 may result in removing Outlook Express from the computer altogether.



CAUSE
If Outlook Express 4.x was not previously installed on the computer, there is no version of Outlook Express to revert to. Internet Explorer can revert from version 5.01 to version 5, but Outlook Express can revert from version 5.01 only to the last full version of Outlook Express that was installed. If Outlook Express 4.x was never installed, there is no full version to which Outlook Express can revert, causing Outlook Express to be removed entirely.



RESOLUTION
To work around this problem, reinstall Internet Explorer from the following Microsoft Web site:

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
