Outlook AddIn in vs2008 questions




I have a simple Outlook 2003 AddIn created using Outlook 2003 AddIn template
in vs 2008. The full code is given below at the end. I got warnings on
Interop assemblies as I have Office 2007 installed while AddIn is 2003 but
as I need to target both 2003 and 2007 I am sticking to lowest common

I installed the AddIn by running the vs 2008 generated setup.

First problem is In Outlook Trust Centre->Add-Ins, my add in is in Inactive
list. How can I automatically make the AddIn active during Setup?

Secondly, when I tick my Add-In under COM Add-Ins and restart Outlook, it
still remains Inactive and under COM Add-Ins it says; Load Behaviour: Not
loaded. A runtime error occurred during the loading of the COM Add-In.What
is the problems or how can I debug this issue?

Many Thanks

End Sub

Private Sub Application_ItemSend(ByVal Item As Object, ByRef Cancel As
Boolean) Handles Application.ItemSend
MsgBox("Item Sent", , "My Outlook AddIn")
End Sub

Did you add the custom actions for setting the CASPOL for full trust for
your VSTO addin? It sounds like you didn't do that.
