Add Outlook Web Addin Function to context menu
问题 Is it possible to add an Outlook Web Addin function to the context menu? As it was possible with the old VSTO Addins: I only find some examples with tab ribbons, like: <!--PrimaryCommandSurface==Main Office Ribbon--> <ExtensionPoint xsi:type="PrimaryCommandSurface"> <CustomTab id="Contoso.Tab1"> <Group id="Contoso.Tab1.Group1"> <Label resid="Contoso.Tab1.GroupLabel" /> <Icon> <bt:Image size="16" resid="Contoso.TaskpaneButton.Icon" /> <bt:Image size="32" resid="Contoso.TaskpaneButton.Icon" />
