I've installed Outlook 2007 beta, used it for a few days.
Wanted to go back to OL2003, uninstalled OL2007.

Now, when I try to start OL2003, I keep getting the following error.
"Cannot start MS Office Outlook. MAPO32.DLL is corrupt or the wrong
version. Please reinstall Outlook".

I tried reinstalling Outlook 2003. Didn't help. I still see get same
error.
Ideas anyone?

With Outlook closed (of course, I know, since you cannot open it), try doing
this:

Click on Start - Run and type "fixmapi" and click OK.

If that does not work, open your Control Panel, open the Mail icon, and then
click Show Profiles. Delete any profiles and then start Outlook.

use system restore to back up to before you installed 2007 then reinstall or
repair 2003.
