even VSTO addins using VSTO 2005 SE with theOutlook2003 PIA's does work

Hi guys.

Please look at the following example:
http://www.add-in-express.com/projec...k2003-2007.zip

It shows on how you can develop VSTO add-in that supports Outlook 2003
and the Ribbon UI in Outlook 2007.
The add-in doesn't require PIAs for Outlook 2007. It uses PIAs for
Outlook 2003 only.
