CAUSES

NOTE: The value of <file name> in the error message above may help in determining which of the following causes applies to your situation.

You have added a new profile for Lotus cc:Mail support and some required files are missing.

You have attempted to switch Outlook from Corporate or Workgroup to Internet Mail Only mode and may have a missing or damaged Mapi32.dll.

You may have either a missing or damaged Extension Configuration File (.ecf), or incorrect information in the Extend.dat file.

You may have a missing or damaged Riched20.dll file.

The file, Nxpext32.dll is missing from your computer, or you removed Netscape Navigator but did not remove the reference to it in the Outlook Add-in Manager.

You installed Crystal Reports for Microsoft Outlook but the path to the Crext32.dll file is incorrect in the Crext.ecf file.

WHAT TO TRY

Missing cc:Mail files.

You should obtain and install the most recent 32-bit VIM libraries from Lotus. These file are available for download at the Lotus Support Web site. In addition, the Export.exe, Import.exe, and Ie.ri files should be copied to the System folder, if you are using Microsoft Windows 95 or 98, or to the System32 folder, if you are using Microsoft Windows NT 4.0. These files are normally stored in the Ccadmin folder on the cc:Mail post office server.
