What is Outlook Express?

Outlook Express is a POP3- and IMAP-compatible mail client with a built-in newsreader. It is available with Internet Explorer for Windows (and is the newsreader in Outlook), or as a stand-alone client for Mac OS 8.1 to 9.x (it is no longer available for Mac OS X). You can configure it to retrieve email from your account via POP or configure it as an IMAP client to access your mail on an IMAP mail server.

Entourage for Mac OS X is an IMAP client with added functionality to more closely resemble Outlook.

Note: At Indiana University, UITS has discontinued POP mail in favor of IMAP. For more information on the POP and IMAP protocols, see At IU, why doesn't UITS support POP mail?

At IU, you must use Outlook Express as an IMAP client. For more information on how to set up Outlook Express to use IMAP at IU, see these Knowledge Base documents:
