MAPISVC.INF problems (client)

If there is an invalid version of MAPISVC.INF in the %windir%\System32 folder, either of the following problems can occur:

To fix MAPISVC problems

  1. Run the program fixmapi.exe, which is normally in the folder %windir%\System32. Note that the program does not appear to do anything when you run it.

  2. Restart the computer.

  3. Test whether the problem has been fixed.

If you continue to have problems

  1. Rename the existing MAPISVC.INF in the folder %windir%\System32.

  2. Copy the version of MAPISVC.INF supplied with Outlook to the System32 folder. This file is normally as follows:

    c:\program files\common 
    files\system\mapi\1033\nt\MAPISVC.INF
    
  3. Restart the computer.

  4. Try the failing operation again.
