My development environment is VS 2005 and VSTOR SE and i have ol2007 installed.

I have developed a very simple addin and it runs satisfactorily on machines
with ol2007. I need to run this addin on machines (client site) with ol2003
also.

I do not want to maintain 2 development environments for each release of
Outlook and require my fellow developers to do the same. Our MS Exchange
setup will only permit ol2007 to be used.

Is there any way to build & release this project for use with ol2003 in my
current development setup?

Any suggestions appreciated.

No. Either maintain 2 dev environments, or develop completely for Outlook
2003 on an Outlook 2003 machine and don't take advantage of later properties
or methods except through reflection and late binding. Or you can abandon
VSTO, but the rule of thumb is that due to changes in various tlb's you
develop on and reference the oldest version of the Outlook PIA you want to
support. So no matter what language you use or platform you still would need
to develop on an Outlook 2003 machine if you want to support Outlook 2003.
