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
