To restore Outlook views, toolbars, menus or settings, you need to reset the content of the OUTCMD.DAT file.
- Exit Outlook.
- 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 DataMicrosoftOutlook”, where “-USER-” if the name of your Windows login account. If not, search your local disk for the filename.
- Rename the “OUTCMD.DAT” file to a different filename.
- Restart Outlook.
Once restarted, Outlook should restore the default OUTCMD.DAT file from scratch and you should be able to use Outlook with its default view settings.
