You can add groups to that tab or create your own tab, you cannot modify or
add to the built-in groups.

Hi Newsgroup,

I'm starting to make me familiar with Visual Studio 2005 and Visual
Studio Tools for Office SE.

I'm able to add user-defined groups and buttons to the Ribbon using
VSTO SE. My question is: Is there a way to add user-defined buttons
also to the default groups as they come with the default installation
of Outlook like GroupNames on the TabNewMailMessage in Outlook?

Your time and help is highly appreciated.

Kind regards,

Steffen
