Many at times Outlook users often have a distasteful encounter of the “Invalid XML” error while using Outlook 2007 or 2010. This only points to a conspicuous fact; that is the error has occurred with some XML file which is associated with Microsoft Outlook.

However, the specific XML file which is the cause of the trouble remains unknown. Interestingly, where there is a problem, there certainly is a panacea. As such, the focal point of this article is to shed light on the possible causes of the “Invalid XML” error and actionable solutions that work correspondingly.

Part 1: The Major Reason for The ‘Invalid XML File’ Error

Usually when Outlook fails to start up and shows the XML file as invalid, it is usually attributed to the XML file for the Navigation Pane Settings having some problems.

When Outlook starts up, a Navigation Pane can be seen on the left side that displays the following; active profile, the top folder, the list of folders in it, along with the other items such as Calendar, Contacts, Notes, etc.

Noteworthy is the fact that the settings and arrangements that you have made here previously are undoubtedly stored at some place. Now this “place” can be located at a default path which entirely depends on the Windows Operating System version you are running on.

If your Operating System is Windows XP, you can locate the default file path navigating from; Documents and Settings\Username\Application Data\Outlook while if your Operating System is Windows Vista or Windows XP, you can locate the default file path from; User\Username\Appdata\Roaming\Microsoft\Outlook

Irrefutably, the major cause why Outlook fails to start up successfully is that the XML file consisting of settings applied on Outlook’s navigation pane is either damaged or corrupted leading to an error message stating that ‘Outlook cannot be started due to an invalid XML file’.

To confirm that this occurrence is sorely caused by the damage of Outlooks navigation pane and that this is the only issue, check whether the XML file size is zero. If it is, then the settings file has been corrupted hence, is the sole reason for the malfunction.
