How to activate the Developer Tab in Outlook 2011

Greetings,

Background:

In Word and Excel 2011, there is a ribbon customization "gear" at the far right of the ribbon, which is used to activate the developer tab. 

This is very easy to find and use. 

However, this icon does not appear in Outlook 2011. 

Searching for this simple option in the typical resources does not yield useful information:

The menu option View/Customize Toolbars provides no options to change the tabs.

Preferences contains no options for Toolbars

In Outlook 2011 Help, the term "developer tab" does not provide any results. Other terms such as "ribbon preferences", which is the term used on Word 2011's "gear" also does not provide useful results. 

If you search on "tabs", the "Customize Outlook window" result only offers the option to minimize the ribbon so that only the existing tabs appear.

When reviewing 

In the KB, ( kb "outlook for mac" "developer tab" ) provides no relevant hits, nor do any number of other searches using terms such as "customize ribbon", etc.
