Hi

I am having a problem in launching the outlook application using from a C#
application.

I have created an outlook addin and created a setup. (VSTO 2005)

I installed the setup. Now when I launch outlook, the addin is getting
loaded properly.

But when I try to launch outlook (2003) from the click of a button of
another C# windows form, the outlook does not load the addin. It sets the
loadbehaviour value in the registry to 2.

There should not be a problem with the code in the addin-as if that was teh
case, the standalone outlook should have also failed.

Is it something to do with security ??

Here is the code snippet I am using.

Microsoft.Office.Interop.Outlook.ApplicationClass app = new
Microsoft.Office.Interop.Outlook.ApplicationClass();

app.GetNamespace("MAPI").GetDefaultFolder(Microsoft.Office.Interop.Outlook.OlDefaultFolders.olFolderCalendar).Display();

It's launching outlook application properly, but, AddIn was not loaded.      
   

Any help will be apprecaited
