add an e-Mail client module into this program. You're already beating Outlook in many other areas.

This is pretty impressive. The reality is that your program is easier on the eyes than Outook and seems to function better. With the proper relationships and validation rules between modules, the only other item missing is an e-Mail module. If you can get an e-Mail module into this product, Outlook is in for a challenge. If that e-Mail module would be able to also connect to Microsoft Exchange, you'll crush Outlook and probably have Microsoft at your door with a massive check.
