The exception message is like this
Unable to cast COM object of type System_ComObject to InterfaceType “Microsoft.Office.Interop.Outlook.MailItem” . This operation failed because the QueryInterface Call on the Com Component for the Interface with ID………..

Error Message :

Unable to cast COM object of type System_ComObject to InterfaceType “Microsoft.Office.Interop.Outlook.MailItem” . This operation failed because the QueryInterface Call on the Com Component for the Interface with ID’{00063034-0000-0000-C000-00000000046} failed due to the following error. No such interface supported (Exception from HRESULT: 0x80004002)
(E_NONINTERFACE)

OK, so look at your code where the error occurs and it will tell you which interface you are trying to access. That will then show what software component is not present on the system in question.

Hi richard, thanks fr ur reply
I am getting exception while trying to access MailItem ex code :
subject = ((Microsoft.Office.Interop.Outlook.MailItem)myInbox.Items[i]).Subject;

can i know what will be the reason for this exception ??

Well I cannot tell you anything more than the information provided in that message. The interface ID does not exist, so some component is not installed on the computer in question.

From the error description it is clear that you need one or more interfaces register at client side, with help of interface id(s) you can register the required interface.

Obviously you try to instantiate an object with a version contained in Office 2010. You must not expect Office 2007 to have that in the same version!
Rather expect Office 2010 to be capable to work with Interop libraries of Office 2007. And that's the way to go: build your application with support for Office 2007.

Thanks for your replies. I solved this.

Actually the exception is because, The outlook contains not only mail items but also calender items,meeting items etc,. hence it is throwing exception when we are trying to access other item as mailItem.
