SYMPTOMS
After installing Microsoft Outlook 2000 in Internet Mail Only mode as an upgrade from Outlook 97, and then returning to Outlook 97, you receive the following error when attempting to run Outlook:

Unable to open your default mail folders. An unexpected error has occurred. MAPI was unable to load the information services Pstprx.dll. Be sure the service is correctly installed and configured.

CAUSE
The original profile used with Outlook 97 contains information that has been changed in the Outlook 2000 account configuration.

RESOLUTION
Rebuild the Outlook 97 profile.

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

MORE INFORMATION
When Outlook 2000 Internet Mail Only is set up, the profile (account) information is migrated from the existing Outlook 97 profile. The profile is renamed "Microsoft Internet Mail Settings." These settings are not converted back when Outlook 97 is reinstalled.

NOTE: In rare cases it may be necessary to replace the existing Personal Folder, also.
