Microsoft Outlook 2010 Crashes At Startup – KB2427204

If you have just installed Microsoft Office 2010 or Microsoft Outlook 2010, Outlook would crash at startup. If you look at the Windows event viewer, you’ll get the following error signatures:

Source: Application Error
EventID: 1000

Application Name: Outlook.exe
Application Version: 14.0.4760.1000
Module Name: Kernelbase.dll
Module Version: 6.1.7600.16385
Offset: 0x00009617

Application Name: Outlook.exe
Application Version: 14.0.4760.1000
Module Name: kernel32.dll
Module Version: 5.1.2600.2945
Offset: 0x00012a5b

This problem usually occurs if you have previous version of Microsoft Outlook installed on your computer and then you upgrade to Outlook 2010. Two files Olmapi32.dll or Mso.dll need to be updated in Outlook 2010 while if you upgrade these files may still be older.

To resolve this issue, only one version of Microsoft Outlook should be installed. You should remove older version of Outlook or if only one version of Outlook is installed, you should repair your Office.
