NOTE: These procedures only apply if you have installed Outlook with the Corporate Workgroup/Other option. This option allows you to use Messaging Application Programming Interface (MAPI) services. To determine your installation type, on the Help Menu click About Microsoft Outlook. In About Microsoft Outlook you should see "Corporate" if you have the Corporate Workgroup installation.



SYMPTOMS
When you start Microsoft Outlook 98, you receive the following error message:

Unable to open your default mail folders. MAPI was unable to load the information service GWMSPI.DLL

If you click OK, Outlook fails to start.



CAUSE
You have installed client support for Novell GroupWise and Outlook 98 on the same computer and messaging services for both products were installed in the same profile.



RESOLUTION
Create two separate Windows Messaging profiles: one for Outlook and one for GroupWise.



MORE INFORMATION
The error message described in the "Symptoms" section occurs regardless of the order in which you install the programs.
