I've got a minimal VSTO Addin for Outlook 2010 with a ribbon. My only goal is to display a ribbon (created via designer) with no functionality. From what little I can tell from MSDN ribbons should just automatically be displayed by default, perhaps with tweaking ControlIdType/CustomId properties for tabs.
Alas, tweaking these properties does nothing -- Outlook loads and displays no tab. A simple message box displayed in the ribbon loader reveals it never is triggered. Additionally, I haven't seen any information resources (tutorials, walkthroughs, overviews, etc..) that say anything about needing to manually tell Outlook to display tabs.
To see the ribbon again, just double-click any ribbon tab, or press CTRL+F1.
To get your ribbon displayed, on the base ribbon in your code change the RibbonType property to be Microsoft.Outlook.Explorer.
