Hi Art,
While it's an install you can do it's not a MS recommended scenario. You'll only be able to have one version of MS Office Outlook
installed in a multi version scenario.
Before going that route you may want to
(a) be sure you have your Office 2003 CD available for later use.
(b) Back up your files/drive before installing.

Would I be able to continue use of my Office 2003 along with testing the 2007 beta?>>
