JimB I am having the exact same trouble as you:

# Installed Office 2007 Beta over Office 2003 Pro
# Uninstalled Office 2007
# Reinstalled Office 2003 Pro
# When trying to open Outlook get 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."
# Have unistalled and reinstalled Outlook.
# Have renamed mapi32.dll and run fixmapi.exe
# Have copied the mapi.dll from another machine using exactly the same
software

No matter what I have tried I have not been able to get Outlook to work.
Would appreciate some help if possible!!!

Cheers,

Jimmy

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.
