OL98: IMO: Installation Does Not Support MAPI Providers

ID: Q214631

The information in this article applies to:
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

Third-party MAPI service provider does not work in Outlook 98 Internet Mail Only (IMO) installation, but it does work in Outlook Corporate or Workgroup (CW)installation.


CAUSE

During the installation process, you have three choices:

The IMO setup installs a version of the MAPI subsystem that does not support MAPI providers. This means that if the user installs Outlook (IMO) they will not be able to use any service providers that are built to the MAPI specification.


RESOLUTION

Install Outlook Corporate or Workgroup installation.


STATUS

This behavior is by design.
