If you have customized settings that you want to replicate on another computer using Outlook, you may want to include the following files in your backup in addition to the personal folders (.pst) file:

  • Outcmd.dat
    This file stores toolbar and menu settings.
  • <Profile Name>.fav
    This is your Favorites file that includes the settings for the Outlook bar.
    Note:
    If you use Microsoft Word as your email editor, signatures are stored in the Normal.dot file as AutoText entries. You should back up this file also.

These files are located in the default Outlook directory.

To open the default folder for Outlook files, go to Start > Run and insert the following path that corresponds to your operating system. Then click Enter to open the folder.

VISTA/Windows 7/Windows 8: %USERPROFILE%\AppData\Roaming\Microsoft\Outlook 

Read the Knowledge Base article on How to export data in Outlook for instructions on backing up the PST file.
