1. Exit Outlook;
2. Locate the OUTCMD.DAT file.
If you are running Windows XP and you installed Outlook on its default path,
you can find the file in "C:\Documents and Settings\-USER-\Application
Data\Microsoft\Outlook", where "-USER-" if the name of your Windows login
account. If not, search your local disk for the filename;
3. Rename the OUTCMD.DAT file to a different filename;
4. Restart Outlook.
Note that you might be navigating through hidden folders above so ensure
