Microsoft has released a white paper to describe how different versions of Office Client will work with MOSS 2007 (SharePoint 2007) Server.  If you are looking at rolling out MOSS 2007 but wonder how your Client Desktops, running Office 2003 or before, might work with MOSS 2007, this document will show you what you can expect from each version (i.e., what will work and what won't).

Here's a link to the document (free) to download: http://www.microsoft.com/downloads/details.aspx?FamilyId=E0D05A69-F67B-4D37-961E-2DB3C4065CB9&displaylang=en
