See if renaming mapi32.dll to mapi32.old and reinstall or repair helps. You
might find various version and locations of mapi32.dll on the system.

I appear to have similar problems as others who have attempted to load
Outlook 2007. After apparently successfully (???) loading Office 2007
beta,
I could not start Outlook. I uninstalled 2007, and re-installed 2003
Office
Pro. I received the 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."

I reinstalled outlook with the same results.
I renamed MAPI32.dll as MAPI32.old and ran fixmapi.exe. No luck

Can anyone supply any other suggestions? I am out of luck and I cannot
access my calendar or messages.
