this is only a partial answer, but I'll extend it if possible
Export custom menus in Outlook 2007 via VBA
I made a screenshot of the custom menus to document the status quo in Office 2007.
With the following VBA code, it was at least possible to export the name and the used macro procedure for each menu entry (print them to the output Window in VBA) which saved me a lot of clicking and copying:
Remark: you have to enter the name of the custom menu, in the below described example, it is called &Special .
Sub ListMenuItems() Dim oCBmnuTools As Office.CommandBarPopup Dim oCBmnuSaveMe As Office.CommandBarButton Set oCBmnuTools = Application.ActiveExplorer.CommandBars("Menu Bar").Controls("&Special") Dim i As Integer For i = 1 To oCBmnuTools.Controls.Count With oCBmnuTools.Controls.Item(i) Debug.Print .Caption & vbCr & .Parameter & vbCr End With Next i End Sub
