Ml3xec16.exe Causes GP Fault in Microsoft Exchange

 Last reviewed: December 28, 1995
Article ID: Q141840
The information in this article applies to:
  • Microsoft Windows 95

SYMPTOMS

When you are using Microsoft Exchange, you may receive the following error message 

   Ml3xec16.exe caused a General Protection Fault in <file name>
where <file name> may be User.exe, Kernel32.exe, or a .dll file.

CAUSE

This error can occur if a 16-bit .dll file that is being called from one of the following files is damaged or is using an old, undocumented, extended MAPI call that is not supported:

  • Msmail.ini
  • Msmail32.ini
  • Shared.ini
  • Shared32.ini
  • Exchng32.ini

RESOLUTION

Rename the Msmail.ini, Msmail32.ini, Shared.ini, Shared32.ini, and Exchng32.ini files to prevent the error from occurring. Then, rename the files one at a time to their original names to determine which file is calling the .dll file. You can determine which .dll file is causing the error by not loading any of the .dll files and then adding them one by one until the error occurs.

MORE INFORMATION

The Shared.ini and Shared32.ini files are located on network shares and are pointed to in the Msmail.ini and Msmail32.ini files. For example: 

   sharedextensionsdir=\\uncname
If the Shared32.ini file exists in the same directory as the Shared.ini file, only the Shared32.ini file is used.

The following .dll files are known to cause problems and are not loaded by Microsoft Exchange: 

   Attmail.dll
   Bcc.dll
   Confcore.dll
   Confplus.dll
   Cssmdel.dll
   Emptyw32.dll
