Scenario 1If you click Yes, the Fixmapi.exe utility starts and attempts to fix the MAPI file conflict by installing the correct version.
If a currently running program is using the Mapi32.dll file, the Fixmapi utility may not fix the file conflict. In this case, the following information dialog box is displayed:
Scenario 2If you click No, there is no change made to the core MAPI file. Because Outlook uses the Mapi32.dll file in the C:\Program Files\Common Files\SYSTEM\Mapi\1033\95 file, clicking No does not affect the operation of the application.
- Quit all open programs.
- Rename the Mapi32.dll file in C:\Windows\System to Mapi32.old.
- Locate the Fixmapi.exe file in C:\Windows\System, and then double-click Fixmapi.exe to run the program.
- Restart your computer.
"Simple Mapi" applications, such as Outlook Express, Eudora, Netscape, and other 3rd party applications install and access the Mapi32.dll file from C:\Windows\System. Applications that support "Simple MAPI" allow you to send documents by clicking Send To on the File menu.
The Mapi32.dll file in the System folder is also used by Microsoft Fax.
If the Microsoft Exchange System Manager (ESM) is installed on your computer, running Fixmapi.exe fixes Microsoft Outlook, but it also breaks the ESM. If you have the ESM installed, please follow the steps in the following article in the Microsoft Knowledge Base:
