I am currently using the Visual Ribbon Editor for CRM 2011 and i am trying to add a button to the Outlook client ribbon (not the web client) that loads the Accounts section of CRM (not in a modal, but the how it would normally load accounts in the main pane) The tabbed section in Outlook is shown in the image below.
I do not have to use the editor, and could use a solution, but i am unsure what sort of command i would need to get it to update the main pane and with either the visual tool or the by hand solution.
Update the HomePageGrid ribbon XML.
Gareth Tucker has written a great tutorial to add a button to the Form ribbon
(just modify where it says Mscrm.Form to Mscrm.HomePageGrid):
