Does OpenOffice.org come with the equivalent of Microsoft Outlook?

No, it does not.

With OOo there is the ability to link various emails programs with OOo (even Outlook & Outlook Express).

Due to recent security concerns with Outlook and Outlook Express it would be better to utilise another email program. There are many to choose from and are dependant on the PC platform you are using.

Also for calendering (PIM) various other programs are available.
