MAPI32.DLL error running Outlook 2003

I do not understand where I am doing wrong. I installed trail version of Office 2007. It is a new Windows Vista system. I had then removed Office 2003 which was previously present. Now in the trial edition everything work fine except Outlook. I am getting mapi32.dll error when I try to start Outlook Express. I tried to add and remove the same but still this did not worked out. I used Windows Cleanup utility which says it might wipe out some non required file, but it does not look working. I need some help on the same. How can I get rid of the same.

This error appears when corrupt or wrong version of MAPI32.DLL is used in your system. You must ensure that you would be able to get the right one. I had found some helpful Microsoft articles from the web. They can simply help you to find number of solutions on this .dll file missing or corrupt issues.

• An earlier version of Outlook is removed, and the newer version of Outlook 2010 or Outlook 2007 is installed unexpectedly when you install an original release non-trial version of a 2010 or 2007 Office suite for a side-by-side installation
• Error message when you try to start Outlook 2003: "MAPI32.DLL is corrupt or the wrong version"
• D2000: ErrMsg: MAPI32.DLL is Corrupt or the Wrong Version
