The following additions have been made to the platforms and requirements documentation for MAPI:
Windows 98, NT, and 2000
The Domino MAPI service providers are available for Windows 98, NT, and Windows 2000. The required DLLs for the Windows messaging subsystem are only available from Microsoft. It is a prerequisite to install Microsoft Outlook 98 or Microsoft Outlook 2000 before installing the Notes client.
The Domino MAPI service providers may only be used to access mail files that use the Domino Release 5.0 mail extended template (mail50ex.ntf).
