Hi I am having problems with my com addin to outlook - it does not use
any Explorer or Inspector, so I think I should be able to do the unloading
inside the onDisconnection.

I have the following four buttons

-------------------------------------------------------
Dim WithEvents previewButton As Office.CommandBarButton
Dim WithEvents reportSpamButton As Office.CommandBarButton
Dim WithEvents reportHamButton As Office.CommandBarButton
Dim WithEvents copyButton As Office.CommandBarButton
-------------------------------------------------------

My onDisconnection sub looks like

-------------------------------------------------------
Dim oOL As Object

Public Sub AddinInstance_OnDisconnection(ByVal RemoveMode As _
   AddInDesignerObjects.ext_DisconnectMode, custom() As Variant)

   'resume on error
   On Error Resume Next

   oOL.CommandBars("Standard").Controls.Item("Copy Message Source to Clipboard").Delete
   oOL.CommandBars("Standard").Controls.Item("Preview Message").Delete
   oOL.CommandBars("Standard").Controls.Item("Report Spam").Delete
   oOL.CommandBars("Standard").Controls.Item("Report Ham").Delete
   Set previewButton = Nothing
   Set reportSpamButton = Nothing
   Set reportHamButton = Nothing
   Set copyButton = Nothing
   Set oOL = Nothing
End Sub
--------------------------------------------------------

I have lookt at the examples at www.microeye.com - but i cannot see why my
code will not unload the buttons.
