MORE INFORMATION

Outlook shares files with Outlook Express.

If you install Outlook with the Internet Mail Only (IMO) option, Outlook does not run if Outlook Express is not installed. If you install Outlook with the Corporate or Workgroup (CW) option, Outlook loses much of its functionality. Shared functionality between Outlook and Outlook Express provides the following key functionalities:
  • Internet Accounts management
  • Secure/Multipurpose Internet Mail Extensions (S/MIME) use
  • Newsreader use
