I'm often asked about this.  People running or supporting customers running Microsoft Small Business Server attend a TechNet Event or a Microsoft webcast, and comment or write to me:

"Hey.. that product you showed is great.  ..but will it work on Small Business Server?"

Well.. sometimes I knew the answer, but often I didn't.  Fortunately, now, the SBS team announced on their blog that their new "Product Compatibility Charts" are now available. 

Check out their blog post for the links to the charts, and for more information.
