Unable To Launch Outlook: Invalid XML Error
One of the main things that can really turn you off is when you are sending a mail-in a hurry and
Outlook just wouldn’t open! More than once, I’ve had the same experience with Outlook and Gmail.

it has really annoyed me when I had to get help from my ill-mannered neighbor. But when
you come to think about it, resolving the issue was far easier than consulting my neighbor!
Invalid XML file detains Outlook from opening
The problem that I faced was that of the error message “Cannot start Microsoft Outlook.
Cannot open the Outlook window.” popping up whenever I tried to open Outlook.
These error messages can sometimes be like “Cannot start Microsoft Outlook. Cannot open the Outlook
window. Invalid XML, the view cannot be loaded”.
There are several reasons for such problems to occur. But it is mostly seen that some Office
2007 Service Pack 2 updates cause this error for certain configurations. But it can occur in
other versions of Outlook as well.
Reasons for this issue
The problem arises when the configuration file for the Navigation Pane gets corrupted. This
causes the failure of the Outlook launch. But like every other trifling problem in Outlook, this
one also can be resolved easily. For this, you can follow the simple guidelines given below:
In Windows Vista and Windows 7, the procedure for resolving this issue is almost the same.
For this, you must first click “Start” and then type “outlook.exe/resetnavpane” and then hit
“Enter”.
In Windows XP the procedure is as follows:0x80070643
Click “Start”, and then select “Run” and type in: outlook.exe/resetnavpane.
There could be other things as well that might go wrong with your PC for this error message to
pop up. So, if the problem persists even after you complete the above-mentioned procedure,
please make sure that you have installed all updates for your version of Outlook. For more
clarification, please contact the Microsoft Live assist team.
