Outlook 2003: MAPI32.DLL error

Problem:  You open Outlook and you get the following error message:

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

Solution:  For some reason, a repair installation doesn't seem to have any effect on this problem, but the solution is quite simple. 

1.  Browse to C:\Program Files\Common Files\System\MSMAPI\1033

NOTE:  For 64-bit OS, the path might be C:\Program Files(x86)\Common Files\System\MSMAPI\1033

2.  Find the file MSMAPI.DLL and rename it to MSMAPI.OLD.

3.  Open Outlook 2003 and all should be well.  A new MSMAPI.DLL file should be visiable.
