You may not be able to use Microsoft Outlook Web Access (OWA) to open, reply to, forward, or delete a message in your Exchange 2000 mailbox. You may receive the following error message in the browser:
The page cannot be found
The page you are looking for might have been removed, had its namechanged, or is temporarily unavailable.
HTTP 404 - File not found Internet Information Services
