I almost never use separate projects, I almost always use just one.

You have to compile on a machine with the earliest version of Office/Outlook
where the code should run. Any later methods or properties added to the
object model can only be accessed using reflection (late binding). Otherwise
the code will run as is on Outlook 2007 when compiled on Outlook 2003.

I Have two projects for 2003 and 2007 outlook.
Is it possible to create a single project which can work both for 2003 and
2007?

1. can I use shared addin project for this?
2. if not .. I want to detect which version of outlook user has at
installation
and run respective setup. how to do that ?
