257824 OL2000: Differences Between Outlook and Outlook Express



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:
 * Internet Mail Only
 * Corporate or Workgroup(
 * No E-Mail installations

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.
