Written by Lucy John on May 02, 2023

Hi, I recently ran into a problem while using Microsoft Outlook application on my laptop. My laptop runs on Windows 7 OS and I am currently using Microsoft Outlook 2007 program. When I went to open my Outlook application, I got error message stating that ‘Cannot start Microsoft Office Outlook; cannot open the Outlook window’. I had never met with any kind of such errors while accessing Outlook 2007 program on my computer, so this looks little strange.

Normally this kind of problems occur when the file that maintains Navigation Pane setting become corrupted. This file is called ****.xml, where **** is the name of your Outlook 2007 profile. This file is stored in the following folder on your system:

  • Window XP:

    C:\Documents and Settings\username\Application Data\Microsoft\Outlook

    Windows Vista and Windows 7:


    If the file size is 0 KB, then it clearly indicates that this file is corrupted. Use the following steps to resolve this problem automatically by yourself:

    • Goto Start menu and click on Run
    • Inthe Run dialog box, type this command: “Outlook.exe /resetnavpane”
    • Click OK
  • The other reasons for Outlook 2007 not opening is running Outlook in the compatibility mode or using a profile created in an older Outlook version or if the Outlook data file (.pst or .ost) was damaged or deleted as a result of incorrect installation or re-installation of Microsoft Outlook 2007

    Anyways, whatever may be the reason, the outcome is same Outlook 2007 PST file cannot be opened.
