MS Outlook has the strange habit of malfunctioning every now and then, displaying some kind of an error message. You might have encountered error messages like ‘cannot start Microsoft Outlook Invalid XML’ or error codes like 0x80042108, 0x80040119, 0x80040600, etc. It might be difficult for an average user to make sense of the cause of the problem from these error messages alone. Instead, you need to use these error messages as a reference for finding a solution to the problem online.
There are plenty of Outlook user forums online, where you will find the solution to such problems. You can also use the error code or error message and search in Google for help.
Dealing with the Invalid XML error
Many Outlook users have come across the error message ‘cannot start Microsoft Outlook Invalid XML’ and this often happens in the MS Outlook 2007 version. Normally, the error happens when you are trying to launch the Outlook application in your system. The application will fail to start and will display the aforementioned error message instead. This indicates that there is some error in the XML files preventing the Outlook application from loading properly.
Such errors can be corrected without much bother if you have some basic technical knowledge when it comes to dealing with such issues. But, the error might be caused by a number of reasons including a software malfunction, virus infection, or some error during the installation of Outlook. And so, the solution to the problem depends on its cause.
One of the troubleshooting steps that you can try in the event of such an invalid XML error is as follows. Go to the Start Menu and open the Run command execution provided there. Type in the Outlook.exe /resetnavpane command into it and press Enter.
This should fix the problem in most cases. For good measure, delete the old corrupted XML file as well before you launch the Outlook application again. Outlook will automatically create a new XML file in its place. So, there is no need to worry about this.
To do that, go to the folder ‘Documents and Settings\… \Application Data \Microsoft \Outlook’. Delete the XML file you find there and launch the Outlook application. Outlook will create a new XML file and everything will run smoothly as it was before.
Also, remember to run a thorough system scan to get rid of any virus infections that might have caused this Outlook file corruption error in the first place.
