Seeking to add custom items to context menu

[simonm]

I am using VS2015 and trying to create an outlook addin to add custom context menu items (when a user right-clicks on a mail item for instance). I have read this article:

https://msdn.microsoft.com/en-us/lib...or=-2147217396

However, I cannot get the GetCustomUI method to fire. Here is my code:

Public Class ThisAddIn
    Implements Microsoft.Office.Core.IRibbonExtensibility

    Private WithEvents myApp As Outlook.Application

    Private Sub ThisAddIn_Startup()
        Try
            myApp = Me.Application
        Catch ex As System.Exception
            Diagnostics.Debug.Print(ex.Message)
        End Try

    End Sub

    Private Sub ThisAddIn_Shutdown()

    End Sub

    Public Function GetCustomUI(RibbonID As String) As String Implements IRibbonExtensibility.GetCustomUI
        Diagnostics.Debug.Print(RibbonID)
        Return ""
    End Function

End Class

Can anyone help me find what I might be missing?

what I might be missing?

Public Function GetCustomUI(RibbonID As String) As String Implements IRibbonExtensibility.GetCustomUI

as far as i can see, this function is not being called, ribbonid has no value, there is no code to actually add items to the ribbon

follow the links on link you posted for some examples

Yes, I realise there is no code to add ribbon items but I need the routine to actually be invoked before I add them and it currently isn't. The article suggests that merely by implementing the IRobbonExtensibility interface it will be invoked.

normally such a function is called in the appropriate workbook open event and the additional controls removed from the ribbon on workbook beforeclose event
