Using Send Command in 16-Bit Program Starts Microsoft Exchange

• Microsoft Windows 95

SYMPTOMS

When you use the Send command in a 16-bit program, Microsoft Exchange may be started instead of the 16-bit mail program installed on your computer.

CAUSE

The Send command is a Simple MAPI function. All 16-bit programs use Mapi.dll for Simple MAPI. When you install Microsoft Exchange, Setup installs the Windows 95 version of the Mapi.dll file. When a 16-bit program calls Mapi.dll, Mapi.dll calls Microsoft Exchange.

RESOLUTION

To use the Send command in a 16-bit program with the 16-bit mail program installed on your computer, replace the Windows 95 version of the Mapi.dll file with the 16-bit mail program's version. Note that reinstalling the 16-bit mail program does not resolve the issue because the Windows 95 version of the Mapi.dll file is newer and is not replaced.

To replace the Windows 95 version of the Mapi.dll file, follow these steps:

1. Rename the Mapi.dll file in the Windows\System folder to Mapi.w95.

   NOTE: The Windows 95 version of the Mapi.dll file is 431K in size with a date of 7/11/95.

2. Obtain a copy of the 16-bit mail program's version of the Mapi.dll file and copy it to the Windows\System folder.
