I have created an Outlook Plugin that works perfectly in Office 2010/2013. It is shown on the main screen of Outlook(where we see all the emails). Somehow it doesn't show up in Outlook 2007.
I have implemented a class using Microsoft.Office.Tools.Ribbon.OfficeRibbon In the ribbon type, I am providing Microsoft.Outlook.Explorer
Is it possible that Microsoft.Outlook.Explorer is not supported in Outlook 2007? Any help would be highly appreciated.
Outlook 2007 uses ribbons only on inspectors. Explorers still used the old Explorer.CommandBars interface. Explorers switched to using ribbons in Outlook 2010.
