When you access an Active Server Pages (ASP) page that uses Collaboration Data Objects (CDO) code to log on to Microsoft Exchange Server using the Session.Logon method, the following error may occur:
[Collaboration Data Objects - [MAPI_E_NOT_FOUND(8004010F)]]
NOTE: This error occurs if you use either Anonymous, Basic or Clear Text, or Windows NT Challenge Response authentication methods as the user authentication on the virtual directory.
This log on error occurs because the user account (either the IUSR_<ComputerName> or the Windows NT account) that accesses the virtual directory does not have permissions to the directory where Windows NT is installed.
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
Following are two work-arounds to resolve this behavior:
When you use CDO in an ASP page, then the .mmp files are created in the Internet Information Server (IIS) server directory where Windows NT is installed by default. The .mmp file is a temporary file that CDO uses to store profile information during the current CDO session. This .mmp file is automatically deleted after the session is closed.
