The information in this article applies to:

- Microsoft Outlook 2000
-------------------------------------------------------------------------------

NOTE: These procedures only apply if you have installed Outlook with
the Internet Mail Only option. To determine your installation type, on the
Help menu click About Microsoft Outlook. In About Microsoft Outlook you
should see "Internet Mail Only" if you have the Internet Mail Only option
installed.

SYMPTOMS
========

After completing an Internet Only setup of Microsoft Outlook on Microsoft
Windows NT SP-3, you may receive the following two error messages when you start
Outlook:

Outlook requires Microsoft Outlook Express 4.01 or greater. You can install
Outlook Express 5.0 by running IESetup.exe from the Internet Explorer folder
where you installed Outlook, or download it from the Internet Explorer site
on the Microsoft Web.

Clicking OK results in a second error message:

An OLE registration error occurred. The program is not correctly installed.
Run Setup again for the program.

Clicking OK to the second error message closes Outlook. Restarting Outlook
results in the same two error messages.

NOTE: This may also occur using Windows 95 and 98.

CAUSE
=====

Outlook with the Internet Only setup option requires Microsoft Outlook Express
in order to work properly; Outlook depends on Outlook Express files.

You can get into this situation by installing Microsoft Internet Explorer 4.01
with the Browser Only option that does not install Outlook Express. Then if you
install Microsoft Office 2000 and choose to not update the browser, you are left
with a version of Office that does not include Outlook Express.

RESOLUTION
==========

Follow the instructions on the first error message and install Outlook Express.

STATUS
======

Microsoft has confirmed this to be a problem in Microsoft Outlook 2000.
