difference between Office Professional 2003 and Enterprise 2003?

I recently ordered a Office 2003 Pro but the CD case says that it is Office Pro Enterprise. I wanted to confirm that before I am going to open it, is there any difference between these 2? Thanks for any information.

Could you please tell me from where did you order it from?

There are some features that differs in Office Professional 2007 and Office Professional 2007 Enterprises although they both have similar kind of applications. You can try to access microsoft.com and key in office pro 2007 enterprise. This edition of Office is for business use with more advanced features included in the same package.

The Office Enterprise is a Volume License version that can e bought through a Company Plan only. It is not available for sale in retail stores, because it is different than the Office Pro version and most version of Office.
