Microsoft Outlook 2003 error (Computer Networking Solution)

Computer Networking Solution: Cannot start Microsoft Office Outlook. MAPI32.DLL is corrupt or wrong version
This morning when I want to open Microsoft Outlook 2003 I got below message “Cannot start Microsoft Office Outlook. MAPI32.DLL is corrupt or wrong version.” It also suggests reinstalling the Microsoft Office Outlook 2003. I did as suggested, I reinstall Microsoft Office Outlook 2003. After reinstall, I open the Microsoft Outlook 2003 BUT I still received the same message “Cannot start Microsoft Office Outlook. MAPI32.DLL is corrupt or wrong version”

I found one forum at http://www.planetamd64.com , they discuss about this issue. Here are the three solutions that the members give.

Solution 1
I was having numerous overall system problems with Office 2007 so I uninstalled the Beta. I had installed it beside 2003 and not as an upgrade. Everything was back to normal except Outlook which I had no option but to upgrade to the 2007 version. After uninstall, I kept getting an error concerning MAPI32.DLL being corrupt or the wrong version and to reinstall Outlook, which I did (I had a full backup of my folders and emails). After the reinstall, I was still getting the same error and Outlook would not open. I did a search and found that the file listed in the error was not MAPI32.DLL but instead MSMAPI32.DLL.

The folder was Program Files (x86)\Common Files\System\MSMAPI\1033. The non-reverted file was 50 KB in size and had a 5/2006 Date Modified. The correct file should be 1,326 KB with a 6/2004 Date Modified. I copied the correct file from another installation and pasted it into the folder listed above. Outlook then opened and the program was just as it was prior to the upgrade to 2007. If anyone has this same problem and you don't have another installation to copy the file from, let me know and I will get it to you. I don't want to take up space at PAMD64 with that size file as an attachment...talker

Solution 2
No need to download any files at all. Just rename the MSMAPI32.DLL to MSMAPI32.DLL.old found below

Drive:\Program Files\Common Files\System\MSMAPI\1033\MSMAPI32.DLL

Start outlook2003 and it reinstalls the DLL and you don't loose anything.


Solution 3
I would reinstall 2007. Export message store, address books, etc. Uninstall 2007. Reboot. Reinstall 2003 and patch it. Import everything back in

I use solution 2 and it worked like a charm. After I rename the file and start Microsoft Office Outlook 2003, the Microsoft Office Outlook 2003 does the short installation and my Outlook open with all the email remain.

I never try the 2 method as I have no time. Maybe you can try it and reply to me.

Cheers
