Unable to open Outlook Window ?

I don’t know the reasons why the outlook window is no opening in my computer. I am a Microsoft Windows XP and outlook 2003 user and cannot start Microsoft office outlook, unable to open the outlook window. I am unable to open the set of folders and need help as soon as possible. Thanks in advance!

It feels very bad if you are unable to access your outlook. The reason behind this problem is the windows program compatibility mode setting that was done when the outlook .exe file was configured. If you set the compatibility for outlook to Windows 95, 98 or ME then the outlook displays the error message. This occurs due to the location of the outlook profile information in the registry which does not matches on the windows XP based computer. It also occurs if the registry key is damaged where the outlook profile settings get stored.

Now to solve this problem you need to,

  • Disable the compatibility setting
  • Delete the Registry Key

To disable the compatibility setting,

  • Locate the outlook.exe. The location where the outlook.exe is stored is:
  • Microsoft Office Outlook 2007 – c:\\Program Files\\Microsoft Office\\Office 12
  • Microsoft Office Outlook 2003 - c:\\Program Files\\Microsoft Office\\Office 11
  • Microsoft Office Outlook 2002 - c:\\Program Files\\Microsoft Office\\Office 10
  • Microsoft Office Outlook 2000 - c:\\Program Files\\Microsoft Office\\Office 9
  • Right Click on Outlook.exe and click on properties
  • On the compatibility tab, click on the clear the Run this program in compatibility mode for check box.
  • Click on OK
  • Restart Outlook. If problem still exist then Delete the Registry key.

To Delete the Registry Key,

  • You can download Microsoft Fix it which is a application that is made to delete registry key automatically. OR
  • You can manually delete the registry. To do so click on start and Run , type regedit and click OK
  • Locate the registry key “ HKEY_CURRENT_USER\\Software\\Microsoft\\Windows NT\\CurrentVersion\\Windows Messaging Subsystem
  • Delete the Profile key under Windows Messaging (subsystem) Key. To do this just right click on the Profile and click delete. Click yes to confirm
  • Exit from Registry Editor and restart outlook.

It everything goes on their way then you will easily open outlook and access all your files.

Good Luck!
