I have a solution with 5 projects in it, one of which is a Windows Form Project. They all are part of the Outlook Add-In. I tried publishing the 5 projects and installing them, which seems to work fine. The only problem is, after installing I see the entry in the Start Menu but only for the Windows Forms project. When I start it, the Form is displayed but not Outlook.
Also, if I open Outlook and look into COM-Addins, I don't see my Addin. How can I publish/install my Addin so it will load automatically when Outlook starts?
Did you create an Outlook 2003 VSTO project? Are your registry entries deployed and is LoadBehavior set to 3?
