Unable to Start Outlook MAPI32.DLL is Corrupt or Wrong Version

Asked By Janis Caldwell 90 points N/A Posted on - 12/11/2012

Hi Experts,

Have a look at the error message below. I received this error message while running Microsoft Outlook.

I installed MS Office 2003 on my machine. After receiving the error message I uninstalled Office 2003 and reinstalled it.

But there is no result. Have you any idea for the issue?

Please help me to solve this problem.

Thanks.

Cannot start Microsoft Office Outlook. MAPI32.DLL is corrupt or the wrong version. This could have been caused installing other messaging software.

Please reinstall outlook.

Unable to Start Outlook MAPI32.DLL is Corrupt or Wrong Version

You can fix this problem just by following these steps: Start your computer. Open my computer. Click on C: harddrive then go to Program Files. From there, search for the Common Files folder and open it. Find the System folder and open again.

Search for the Msmapi folder then open it. Lastly, go to the 1033 folder. Once there, find the MSMapi32.dll.

Right click on it and then rename it into Msmapi32.old.

Launch your program again then you’re good to go.

Hi JANIS, 

 

This issue more often than not occurs when you installed a beta version of outlook. After you uninstalled the Beta version the file mentioned in the error will not be removed and hence this issue.

 

If my presumption is correct then you may try to do the steps below.

 

1. Start Windows Explorer.

2. Locate and then open the following folder on your computer:

C:Program FilesCommon FilesSystemMsmapi1033

3. Right-click the MSMapi32.dll file, and then click Rename.

 

Note The file (Msmapi32.dll) that you are renaming differs from the file (Mapi32.dll) that is mentioned in the error message.

4. Type Msmapi32.old, and then press ENTER to rename the file.

5. Start Outlook 2003.

 

Keep us posted!
