   Hi Robert,

   You need to have Outlook 2007 installed to properly run the add-in I am currently working on (started with the code seen in the post – which of course has later been heavily modified and added to, for example by replacing the Outlook 2003-compatible CommandBarButton with a Ribbon group).

   However, the code in this post should also work with at least Outlook 2003 and 2010. It does work with the Outlook 2007 trial version, which has been used to test it on a local machine here. I don’t know if it works with for example free Outlook Express, as I am currently only developing it for Outlook 2007.

   I install the Primary Interop Assemblies for Microsoft Office 2007. I was able to add the reference to the Microsoft.Office.Core but there was no reference for Microsoft.Office.Interop.Outlook. What am I doing wrong. Do i need to install the trial version of office 2007?

   Microsoft.Office.Interop.Outlook comes with the Office 2007 installation – as far as I know you can’t get it separate.

   Do I need to install outlook 2007 to get access to the IDTExensibility Assemblies? How do I add this reference so I can add the line:

   using Extensibility;

   To my code.

   You can add a reference to the Extensibility under the .NET tab, with the name “extensibility”. In other words, it’s not under the COM tab with the Office references, and only called extensibility, without “IDT” in the start. There’s some information from MS at http://support.microsoft.com/kb/302901
