I found the problem!

By default the file Interop.Microsoft.Office.Core.dll was not included
in the release!

Once included it works fine.

Hello,

I'm still struggling with my outlook addin.

I'm developing an add-in for multiple versions of Outlook.

It is build with VB.NET, using the Shared-Add-in project. I created it
using Microsoft Outlook 10.0 Object Library (Outlook 2002 aka 'Outlook
XP')

The OnConnection Event works fine.

The OnStartupComplete event works fine on Outlook XP but on Outlook
2007 it has this problem...if I include the line with the
ActiveExplorer variable the event never fires! :-(

What it can be?

Here is the portion of code:

*Private _applicationObject As Object
*Private _addInInstance As Object
*Private _outApp As Outlook.Application
*Private WithEvents _activeExplorerBars As
Microsoft.Office.Core.CommandBars

*Public Sub OnStartupComplete(ByRef custom As System.Array) Implements
Extensibility.IDTExtensibility2.OnStartupComplete
* * * * Log("OnStartupComplete.Begin")
* * * * _outApp = DirectCast(_applicationObject, Outlook.Application)
* * * * Log("AppDetails." & _outApp.Name & " " & _outApp.ProductCode)
* * * * '_activeExplorerBars = _outApp.ActiveExplorer.CommandBars

* * * * _activeExplorerBars = Nothing 'REMOVING THIS LINE OF CODE
MAKES OnStartUpComplete To FIRE!

* * * * Log("OnStartupComplete.End")
* * End Sub
