PST Repair after ScanPST MSMAMP31.DLL Error

You were using Outlook 2003 and in order to get better features you have upgraded it to Outlook 2007. But when you tried to open Outlook you got an error message stating that “PST file is corrupted. Run Scanpst". After getting this message you tried to repair your PST file by using Inbox Repair tool, but surprisingly you got another error message like “This application failed to start because mapi32.dll was not found. Re-installing the software may fix this problem." At that point you may not understand what does this Mapi32.dll error mean and why your system is displaying such message.

However, the Mapi32.dll is nothing but Dynamic-Link Library is a file, which is used by many different email applications and can be written over if you have installed an email program in addition to Microsoft Outlook. The mapi32.dll error happens when upgrading Microsoft Outlook for example, from Outlook 2003 to Outlook 2007 or when moving from Outlook 2007 to Outlook 2003. This error may also happen if you uninstall and then reinstall Outlook 2007 on a computer that previously had Outlook 2003. During the process of up gradation or installations, the mapi32.dll file will be not replaced and it causes incompatibility issues. Microsoft has recognized this issue and supplied a fix together with the Windows operating system. In order to fix the problem follow the instructions given below:

  • Click “Start” Which you can see at the left side of the Window
  • Click “Computer” and go to the C drive.
  • Navigate to “Program Files”, then “Common Files”, then “System”, then “MSMAPI” and then the “1033” folder.
  • Right-click the file “Msmapi32.dll” and click “Rename”
  • Rename the file as “Msmapi32.old” It serves as a backup of the file
  • Start Microsoft Outlook. When Outlook is started, one of the files looks for the “Msmapi32.dll” If Microsoft Outlook does not find the file then it repairs itself and recreates the file that's compatible with the current Outlook version
