Outlook 2011, 2013, and 2016 are graphical email clients that accesses mail on remote servers. To use Outlook, you need an account on either a mail server running IMAP or POP, such as pobox, or a Microsoft Exchange Server. Note that Outlook 2013 and Outlook 2016 are not supported as a IMAP/POP clients and are discouraged because Outlook is not optimized for IMAP/POP.

For PennO365 Outlook users, there are two versions of the product--the "click-to-run" version which is tied directly to a PennO365 account, and a volume licensed version which is installed and activated with the use of a Product Key. As patches and new features are more rapidly added by Microsoft to the "click-to-run" version of Outlook than to the volume licensed version, "click-to-run" is the preferred version for the best PennO365 experience.
