I have a an Outlook Add-IN that is created via IDTExtensibility2 and results
in a Button in Outlook, that starts our in-house developed application. This
has worked fine and is developed w/ VS 2003/C# and runs in Outlook 2003. Our
app is started in the Outlook Add-In via:

GuiApi m_objGuiApi=null;

then:

m_objGuiApi = new Interop.OurAppGui.GuiApi();

In Outlook 2003/XP, works fine with or without the application running, in
Outlook 2007/Vista, I can connect if application is already running, but if
not running, it is not created via the new above - no error message just
nothing.

I see there are new security issues w/ Outlook 2007 and wondering if that
has something to do w/ it. Any suggestions? Thanks in Advance... Scott
 
Outlook 2007 security is actually weaker than in earlier versions,
particularly if an up-to-date AV scanner is installed. My bet is your
problem is with Vista security. See if you have the same problem with
Outlook 2003 on Vista. If you do then post in a .NET or Vista group to find
the recommended way of starting your app under Vista.
