SYMPTOMS
When using a computer with both Eudora Pro and Microsoft Outlook installed, you receive the following error message:

A recently installed program may cause Microsoft Office or other e-mail-enabled programs to function improperly. Outlook can resolve this conflict without affecting the program that originally caused the problem. Do you want Outlook to resolve this problem?

When you click Yes, you receive the following error message:

Outlook was unable to resolve the conflict between a recently installed program and Microsoft Office or other e-mail-enabled programs. Outlook needs to modify a system component that another program is currently using. To fix this problem, please restart Windows.

After receiving these two error messages and following the instructions, the messages reappear each time you start Outlook.



CAUSE
The Messaging Application Programming Interface (MAPI) server setting in Eudora is set to Always. This means that Eudora handles all Simple MAPI services, sending files as attachments in non e-mail enabled programs.



RESOLUTION
In Eudora, change the MAPI server setting to either When Eudora is Running or Never.

Changing the MAPI Settings in Eudora
To change the MAPI settings in Eudora, follow these steps:


 * 1) On the Tools menu in Eudora, click Options.
 * 2) In the Category list, click MAPI.
 * 3) Under Use Eudora MAPI server, click either When Eudora is Running or Never and then click OK.
 * 4) Quit Eudora and restart Outlook.



MORE INFORMATION
In its implementation of MAPI, Eudora uses two primary files:
 * Eumapi.dll - Provides Simple MAPI services to 16-bit programs
 * Eumapi32.dll - Provides simple MAPI services to 32-bit programs

When you start Eudora, it checks for the existence of the Mapi.dll and Mapi32.dll files, usually found in the Windows\System folder. If these files are present, it copies Eumapi.dll and Eumapi32.dll into the System folder as Mapi.dll and Mapi32.dll. It renames any existing versions of these files to Mapi.000 and Mapi32.000 respectively.

If the Eudora setting is Always, the files are not renamed to their original names. If the setting is When Eudora is Running, the files are renamed to their original names when you quit Eudora.
