Searching The Cause Of The Invalid XML File Notification

According to Microsoft explanations, the actual reason for this issue is a tainted Navigation Pane settings record – profilename.xml, where profile name is the name of your Outlook ID.

No one knows exactly, why this happens, yet all editions of Microsoft Outlook from 2003 to the most current Outlook 2019 might be affected by this error parsing XML issue.

You may want to start resolving the problem by checking these few things first. Check the file’s size in one of the following folders:

either C:\Documents and Settings\username\Application Data\Microsoft\Outlook (On Windows XP)
or C:\Users\username\AppData\Roaming\Microsoft\Outlook (On Windows Vista & 7).

If it is 0 KB, then you have found the root of the problem.

To solve it, make sure to follow our tips:

  • press Win + R to go to the Run command prompt;
  • type Outlook.exe /resetnavpane in the edit box, and press Enter;
  • see whether the invalid XML problem got fixed.
