Cannot start Microsoft Outlook. MAPI32.DLL is corrupt or wrong version

We had an issue where a user decided to install his home office 2007 copy onto his work machine and obviously we got a report saying so. Since we aren’t licensed for that the obvious answer was to uninstall and reinstall outlook 2003.

Upon doing so an error would pop up and outlook seemed completely broken, the error was referencing Mapi32.dll and Mapi32.dll is located at c:\windows\system32\Mapi32.dll
This is not the correct file however, nomatter if you rename or delete this it wont fix the issue.

The offending file in question is MSMAPI32.dll in C:\Program Files\Common Files\System\MSMAPI\1033. Rename or move or delete this file then reinstall office 2003 and you are good to go.

Error Message:

Cannot start Microsoft Outlook. MAPI32.DLL is
corrupt or the wrong version.  This could have
been caused by installing other messaging system.
Please reinstall Outlook.
